1 Peter 1:14
As obedient children, do not conform to the evil desires you had when you lived in ignorance.
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 thought, we were completely stupid. Scripture tells us not to be 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 the opportunity to say "Hey Stupid" to you. Seek to be pleasing to Him in all you do. Focus on Him when making decisions, ask Him what you should do, we wise!
