Jesus knew no sin. How many times during the day do you sin? Can you imagine, no sin, a perfect person, Jesus. He became sin on the cross so that we could be forgiven. Take the time to thank God for sending his only begotten Son for us. We really cannot comprehend his love for us.
For he hath made him to be sin for us, who knew no sin; that we might be made the righteousness of God in him.
2 Corinthians 5:21
