Read: 1 John 3:19-24
This is how we know that we belong to the truth and how we set our hearts at rest in his presence: If our hearts condemn us, we know that God is greater than our hearts, and he knows everything. (1 John 3:19-20)
And this is his command: to believe in the name of his Son, Jesus Christ, and to love one another as he commanded us. (1 John 3:23)
This passage answers some of the questions raised earlier in verses 6 and 9 of this chapter, which say that Christians stop sinning. According to John, if my heart feels guilty, then my feeling shall be corrected by my mind, which knows that God is greater than my heart, greater than my shame.
I stop sinning because Jesus has taken away my sin (3:5). Jesus did this by fulfilling the law; not abolishing it (Matthew 5:17), but refining and redefining it in himself.
Jesus said the whole law is summed up in two commands: to love God with all my heart, soul, mind and strength; and to love my neighbour as I love myself (Matthew 22:37-40; Mark 12:29-31). Now John reframes this summation of the law. John says, paraphrasing Jesus (John 6:29), that God’s commands are two-fold: to believe in the name of God’s Son, Jesus Christ and to love one another.
If I consider the parallels between these two two-fold summations of the law, I can see how the second interprets the first. John’s “one another” defines Jesus’ “neighbour” as fellow believers, I think, based on John’s previous use (3:10, 3:16) of “brother and sister”. (Which doesn’t mean that Christians should not love non-Christians, merely that this love is not a primary command.)
Likewise, “believe in the name of his Son, Jesus Christ” clarifies what it means to love God with all of our heart, soul, mind and strength. We love God primarily by believing in His Son.
And when I believe in God’s Son Jesus, I know that God is greater than me and he has sent his Son to take away my sin. I stop sinning because my sin is no more – abolished not by the abolishing of the law, but by its fulfilment by Jesus Christ. Sin is lawlessness (3:4) and since the law is fulfilled in Christ and through my belief in him, there can be no more lawlessness in me, no more sin in me.
Aaah! Now my heart is free to rest.
God is great and the good news about his Son gives rest to my heart.
LORD God Almighty,
Great is your name; great is your glory.
You are greater than me; greater than the condemnation of my heart within me; greater than anything I can conceive or imagine; greater than infinity.
You are greatly to be praised.
I believe in the name of your only Son, Jesus Christ, my Lord.
I believe that somehow you, who are more-than-infinite, became less, lowly, a human infant born of the virgin Mary, conceived by your Holy Spirit’s essence.
I believe that Jesus suffered cruelly according to the decision of Pontius Pilate. I believe Jesus was crucified on a Roman cross; that he died there at Golgotha, the place of the skull. I celebrate this as Easter Friday.
I believe that the body of Jesus was buried in a fresh grave by those who sought to honour him.
And I believe that Jesus rose again to life on the third day, which I celebrate as Easter Sunday.
I believe that Jesus was seen alive by honest eyewitnesses before he ascended to heaven, to the God-realm. I believe Jesus is sitting even now at your right hand. I believe that one day Jesus will return to earth to judge all people, including those who have already died and those still alive on that day.
I believe, LORD. Please deepen my belief in the name of your Son, Jesus Christ.
