2 Corinthians 5:17
Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new.
Those who are born again become a new creation. We are apt to think that since we are saved, we will no longer struggle with old habits, evil thoughts, and fleshly lusts. This verse does not describe a believer’s practice but their position in Christ. In Christ, old things have passed away and all things have become new and as we progress in our Christian life, our practice will increasingly correspond with our position. One day, when Jesus returns for us, our practice and position will be in perfect agreement.
