1 John 2:1-3 CSB
My little children, I am writing you these things so that you may not sin. But if anyone does sin, we have an advocate with the Father — Jesus Christ the righteous one. He himself is the atoning sacrifice for our sins, and not only for ours, but also for those of the whole world.
This is how we know that we know him: if we keep his commands.
