As obedient children, do not conform to the evil desire you had when you lived in ignorance.
I Peter 1:14
When we think about our lives before Christ I don't think ignorant is what first comes to mind. Can you imagine telling a lost person how ignorant they are? It truly makes sense though, we were completely stupid! And scripture tells us not to be that stupid again! How will we make sure to make wise choices? Stay in the word, hold true to what it says. Not that He would, but don't give God a chance to say, "Hey Stupid" to you. Seek to be pleasing to Him in all you do. Give Him that opportunity to say "Hey Look - That is my child in whom I am well pleased!"
