My dear children, I write this to you so that you will not sin. But if anybody does sin, we have one who speaks to the Father in our defense—Jesus Christ, the Righteous One. He is the atoning sacrifice for our sins, and not only for ours but also for the sins of the whole world.
1 John 2 v 1-2
Christians still mess up and sin. But God has given us the ultimate solution to sin — Jesus Christ. He sacrificed His own life to atone for our sins — to make things right with God. If we trust in Him, Jesus comes to our defence. We’ve all sinned and deserve God’s punishment, but Jesus is our defence lawyer — pointing to His own death in our place to rescue us from the death sentence.
