"The Son of God loved me and gave himself for me" (Ga 3:20). That sentence makes this whole present world too small an arena in which to praise God. The joy it gives requires a new heaven and new earth in which to express it. Gone are the fear, suspicion, guilt, anger and sense of grudging obligation born of the law. They are replaced with the love, joy, peace, patience, etc. which is the fruit of the Spirit (Ga 5:22). This sentence stands at the center of my life and forms the motivating power of all I now do. The Gospel heart is the heart set free.
