I am not ashamed: for I know whom I have believed, and am persuaded that he is able to keep that which I have committed unto him against that day. 2 Timothy 1:12
To be shamed is to feel that one’s humanity has come into question. Our human nature does not like to feel shame, great pains will be undertaken to avoid this feeling. We hide from all that will shame us whether that is our behavior or a sinful act exposed. The apostle says that he is not ashamed, no matter how the world would scoff or mock, in Christ we can have great boldness that our sins will never haunt us with the specter of shame.
Conjoined to his boldness, he mentions the hallmark of the Christian life. We must truly know him who we have believed. To know Christ is to know that he is trustworthy and he has canceled our sin debt. Our sins will never shame us by being exposed, as they are removed from us and his righteousness is imputed to the believer. If you are truly persuaded that Jesus is the Christ, then he must be able to keep that which we have committed to him, our very lives. To stop here is to truncate our Savior’s job, he has promised us that we will not feel shame, and that we will not stand judgment rather he is faithful to remove our sins and present us to the Father. Knowing him is trusting him.
