The process of becoming the Christian you want to be is to stop being the Christian you presently are.
Think and choose. Remember and apply. Stop simply reacting to emotion. Stop staring at circumstances.
The Spirit of Christ does not live in the flesh. He is in heaven and from heaven.
Think Eternity. Look at Him. Listen to what you see. Don’t bother to look at your failings. Since when have they delivered you any profit?
Set your mind and your soul on Christ. You will only prosper as much as you make that your life.
