The apostle John in a message to his fellow Christians wrote: “My little children, these things write I unto you, that ye sin not. And if any man sin, we have an advocate with the Father, Jesus Christ the righteous. And he is the propitiation for our sins: and not for ours only, but also for the sins of the whole world.” (1 John 2:1-2)
First, it is to be the goal of every Christian to rise above sin—to make every effort to purge it from our lives.
Second, when we fail and do sin, all hope is not gone. We have Jesus who is totally sinless as our advocate. He will speak to God for us. Also, He is the propitiation for our sin. That is, He is Himself the offering for our sin.
Third, not only is Jesus the propitiation for our sins but also for the sins of the whole world. That is, everyone in the whole world has the opportunity to become a Christian and have the forgiveness of sins. But how are they to know? That’s where we come in. It is our responsibility to tell the story.
