Threats and promises often go together. We have the threat of sin, its penalty and its punishment. We have the promise of God’s forgiveness and the fullness of His blessing. The sin question has to be settled. No man will turn from his sins until he sees the exceeding sinfulness of what he is doing.
This is seen best when he looks at the cross. The deepest tints and the most remote ends of sin are exposed when the world crucifies Jesus Christ. He was God in the flesh, and He became sin for us, who knew no sin, that we might be made the righteousness of God through Him.
The wages of sin is death, and Jesus received those wages on the cross. Woe unto the man who rejects Christ. How shall we escape if we neglect so great a salvation?
After the threat has been passed, the promise comes into focus. “If we confess our sins, he is faithful and just to forgive us our sins and to cleanse us from all unrighteousness.” The promise is that He is with us always, even unto the end of the world. He that is within us is greater than he that is in the world.
