The difference between condemnation and conviction is that condemnation is the voice that will look at your sin and say, "look at what you have done!" – conviction is the voice that will look at your sin and say. "look at what Jesus has done!"
There is therefore now no condemnation for those who are in Christ Jesus – Romans 8:1
One will point at your error, the other will point at the one who died as the solution for your error.
