Paul tells us in Romans about the struggle he had with the flesh. He always wanted to do right, but found himself doing the wrong things. He knows what is right, but doesn’t always live up to that standard. We have the same struggle and as long as we are in this tent of flesh, we will always have it. We have to put to death our fleshly desires and focus on Jesus. The devil wants to keep us “sin-minded'”, but we need to follow after God’s Holy Spirit and be “Christ-minded”. If we have the mind of Christ, His attitude, and if we always try to see things through His eyes, then we can focus on things above and those fleshly desires will become less and less important. This does not mean that we live in some fantasy world, but rather, that the things of Christ become more real to us as we mature in our journey with Him.
