Do we have to sin? What a question. Here's another one: are we sinners trying to act like saints, or is it possible that we are saints who have the ability to choose sin? — God. Is. Faithful. Three words that change everything reminding us that sin is not the end of our story. God has provided a way out so we can endure and escape the temptation to chose anything other than Him. So, do we have to sin? No. Do we need the grace of God? Yes. Do we need the mercy of God? Yes. Do we need the forgiveness of God? Yes. But do we have to sin? No.
