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 2:1-2
John wants to prevent even one sinful event in the lives of those he loves and those who seek to honor Jesus. He is concerned because he knows that even one sinful event can be used by Satan to discourage and defeat us and hurt those we influence. We need to know that we have a Savior and a defender. This Savior, this Defender, paid the price to redeem us. He sent his Spirit to help us overcome sin’s power. He is our intercessor who will speak to the Father and claim that right to forgive us and make us holy and make us his!
