In Christ we are made new. Therefore, we need to stop thinking like our old selves and start thinking new life thoughts and doing new life things. This is a challenge for us because it is like starting all over again in life; like learning how to walk all over again.
However, we are not alone as learn to live a life that is new. Our Heavenly Father has promised to us a guide that will teach us and encourage us as we press on. That teacher is the Holy Spirit and it is important that we heed His words and His advice as we learn to move in our new bodies. Otherwise, our progress in our walk will go a lot slower than we want and we will miss out on all the things God has for us.
