The song “Amazing Grace” was written to illustrate a sermon by John Newton on New Year’s Day of 1773. He was a slaver, a human trafficker of the worst kind – until he met Jesus. “Christ Jesus came into the world to save sinners – of whom I am the worst” (1 Timothy 1:15 – https://bit.ly/2Qpydv2).
Maybe you’ve done some things this year that you’re not proud of (and that Jesus would not be proud of). Nothing is wasted in the kingdom of God, even your worst mess-ups. Confess them to Him. It’s not like He didn’t see it anyway. He can use anything to build His kingdom – even your mistakes (just ask John Newton).
