18 Little children, let us not love in word or talk but in deed and in truth.
19 By this we shall know that we are of the truth and reassure our heart before him; 20 for whenever our heart condemns us, God is greater than our heart, and he knows everything. 21 Beloved, if our heart does not condemn us, we have confidence before God; 22 and whatever we ask we receive from him, because we keep his commandments and do what pleases him. 23 And this is his commandment, that we believe in the name of his Son Jesus Christ and love one another, just as he has commanded us. 24 Whoever keeps his commandments abides in God, and God in him. And by this we know that he abides in us, by the Spirit whom he has given us.1 John 3:18-24
It has been a few weeks since we have been in 1 John together, and I think that today’s passage is quite an appropriate diving board for us to get back into the swing of things.
Part of the purpose of 1 John is to help people know that they have the Life of Christ, that the Light of Christ has shone on them, and that the Love of Christ has been extended to them. That knowing is called assurance, which basically means that we can be sure – we can truly know – that we are children of God. Throughout the first half of 1 John, the idea of walking with Him in the light “as He is in the light” (ch. 1:7) and abiding in Him and His truth (ch. 2:27) is used to help us see what it means to be God’s children who do not have to “shrink from Him in shame at His coming” (ch. 2:28). Today’s passage continues that in helping us have confidence in His promises to know who we are in Him, and more especially whose we are – His, even in the presence of doubts.
Doubt, believe it or not, is not necessarily a bad thing. It can keep us real and honest. It can make us double-check our motives. But it can also freeze us up and make us ineffective. There are five truths in today’s passage that can either help overcome our doubt or show us that we need to repent – both of which are blessings in and of themselves. If, through the reading of God’s Word, His Spirit lets you know you have no reason for doubt, you will no doubt feel blessed. But, if through reading He shows you that you are not His, this is a more gracious blessing than we could understand in the moment.
It is my prayer that whichever you find – doubt or repentance – that you, ultimately find yourself closer to Him.
Truth #1 – Love Reassures Our Hearts (vv. 18-19)
Verse 18 is like a hinge of a door, opening up from John’s discussion about the love of Christ and how it does (or does not) show up in our lives. I believe that we underuse this verse and just kind of tag it onto other verses to prove what we want to say. Look at what it says about how we should love – it does not exist in “word or talk” but in one’s actions, “in truth”. I work with kids every day who are not fooled with the words of love – they understand what love is through experience, through truth.
In the case of the love John speaks of here, it is the love that comes from Christ (Romans 5:8, Galatians 2:20). Those who are in Christ (who is Himself the Truth – John 14:6) have experienced His sacrificial, never-failing, never-ending love. And part of being in Him is sharing the love that He has given us with others –
“He laid down His life for us, and we ought to lay down our lives for the brothers” (ch. 3:16). Loving others with Christ-like love trumps any “I love you”, it triumphs over any promise or lie but is true through and through because He said it was:
“This is my commandment, that you love one another as I have loved you. Greater love has no one than this, that someone lay down his life for his friends. (John 15:12-13)
The Truth has spoken on the matter, and, when His love shows up in our lives and practices, our doubting hearts can be reassured that they belong to Him.
Truth #2 – God is Greater Than Our Hearts (v. 20)
Rather than diving into an analogy or illustration, I think we need to get down to the truth regarding our hearts. “The heart is deceitful above all things, and desperately sick” (Jeremiah 17:9). Our hearts lead us to sin. Despite what we would want others to believe, we enjoy sin (just not necessarily the consequences that come with committing it). Sin is the sum of our heart’s desires. Yet the most common advice I hear given to people who are seeking truth or counsel on big decisions in their lives is for them to follow their hearts!
In the context of today’s passage, John talks about the heart acting as our conscience. This can be a good thing, but, remember, the heart is “deceitful” and knows how to trick you better than anything else because it is truly and foundationally you. Why else would our hearts lead us to sin that leads only to heartbreak? Why else would pursuing the “loves” (word and deed) that end up being lusts?
Sometimes, our heart – our conscience – cues us into something wrong. And, in those times, it serves us well. But, sometimes, our heart merely aches because we do not get what we want – that missed opportunity, that time you chose this over that, that time you could have gotten ahead and could have prevented so many struggles. Jeremiah 17:9 ends with a question: “Who can understand [the heart]?” Today’s passage answers that: “God is greater than our heart” (v. 20).
You see, when one repents and believes in Christ and becomes born again, God performs a heart transplant. He gives a “new heart” and a “new spirit” to replace “the heart of stone” (Ezekiel 36:26). I have already said that our hearts give us what we want whether or not it is what we need, but the new heart that God gives us beats for Him and what He knows we need. He alone is the one who “search[es] the heart and test[s] the mind” so that He can know who we are and whose we are (Jeremiah 17:10).
So, if your heart – your conscience – is condemning you because you have sinned, it is God working in you to bring you to repentance. But, if your heart is doubting and dragging you back into former sin, be reminded that “God is greater than your heart” and what He says about you is what matters into eternity.
Truth #3 – Prayer and Assurance Go Together (vv. 21-22)
I remember vividly receiving my first Walkman and Garth Brooks’ debut album. If I close my eyes, I can take myself back to walking around the yard and having the music pour directly into my brain (no doubt too loud). There was a song on that album whose lyrics try to speak to me even some thirty years later: “Some of God’s greatest gifts are unanswered prayers…”. While this is a song about a man reminiscing on an earlier love not coming about in the light of his current romance, it illustrates John’s point here. How we pray and what we pray for – counting our motivations and desires and hopes – shows our hearts and can either reassure us that we belong to Christ or not.
John, here, illustrates that those who are in Christ have “confidence” to come “before Him” that leads to an openness in prayer (v. 21). That confidence is not in ourselves or our actions but in the fact that He has produced a change in our lives that led us to “keep His commandments and do what pleases Him” (v. 22). When you pray, are you seeking the Lord’s will and wanting what He wants? The answer to that question will either reassure us, drive us to repent, or condemn us. May we find confidence in what He has done in us.
Truth #4 – Biblical Beliefs Produce Biblical Results (v. 23)
Truth in the world today is subjective. I hear more and more people saying things like “this is my truth” or “it is the truth to me”. True truth does not work like that. And Biblical truth does not deviate from what the Bible says because it shows Jesus saying that He is the Truth (John 14:6) – that He is “full of grace and truth” (John 1:14). And, if it is lying about Him, nothing is true.
John references “His commandment” in verse 23. He speaks of this with respect and authority, almost as if acknowledging Jesus’ authorship of the Word in the way He says it. Jesus’ commandment here is two-fold: 1) “we believe in Jesus Christ, and 2) we love one another (“just as He has commanded us”). If you have doubts and need reassurance, this truth gets to the heart of the issue. If you do not believe that Jesus is who the Bible says He is, you cannot be saved (Romans 10:9). He is strong enough to take our questions and our doubt, but what His Word says about Him is true or it is not. The way that John writes this in the original language shows how we can truly know if we believe this: love. Belief, or faith, in Christ is an action that is defined by whether we continue on (ch 2:19, 3:10) in Him, whether or not His love shows up in our lives. This is where it gets tough and ,trust me, I have to wrestle with this more often than I would care to admit, because it is easier to hate others or love myself than love God and show His love to people.
Ultimately, you know how this plays out in your life. Does it lead you to reassurance or repentance?
Truth #5 – Only His Children Have His Spirit (v. 24)
As I type this section, I can hear my father-in-law singing John 15 as a song; look at verse 5: “I am the vine; you are the branches. Whoever abides in me and I in Him, He it is that bears much fruit, for apart from me you can do nothing.” The final truth to reassure our hearts is whether Christ – His Spirit – abides (lives, dwells) in us. Paul says it thusly in Galatians 5:16, “walk by the Spirit, and you will not gratify the desires of the flesh”.
John here carries out the same analogy that Jesus did in his gospel. He shakes our tree to examine our fruit. If He is not abiding in us, our fruit is sinful, rotten, dead. If His Spirit is in us, His fruit is evident – “love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, self-control” (Galatians 5:22-23). Are you connected to Christ? Are you rooted in Him? Is the fruit of His Spirit growing in your life?
I stated at the beginning of this week’s devotion that rooting out doubts would either lead to being reassured – finding renewed confidence in Christ – or it should lead to repentance. Maybe, after reading through 1 John 3:18-24, you have come to realize that you do not belong to Christ. Maybe the fruit – the proof of His Spirit, His love – is not in your life. Let me assure you of this: it can.
The Bible tells us that “if you confess with your mouth that Jesus is Lord and believe in your heart that God raised Him from the dead, you will be saved” (Romans 10:9). So, if you have found that you do not have Him and want to receive Him, call out to Him and be saved.
If you read these verses and find that you are in Him but need to repent of sin and walk with Him in love and truth again, let the words of the writer of Hebrews be a comfort and guide to you: “Let us then with confidence draw near to the throne of grace, that we may receive mercy and find grace to help in time of need” (Hebrews 4:16). No matter how far you have strayed, He has not moved. He is still on His throne. And His throne is one of grace where you can surely receive mercy and find grace – where you can surely find Him. Beloved Sojourner, know that I am praying for and love you. If you need to talk, need someone to listen, or would like to pray, I am here for you and would love to point you to the throne of grace today.
