When we drift away from God we initially do not even know it is happening. We may remember a time in our lives that God meant so much to us. Time away from God is like time away from using a tooth brush. Eventually decay will set in. We become apathetic towards God. He no longer matters to us.
God is not interested in what we were but who we are. As Christians we are still His children. He longs to fellowship with us. Don’t keep Him waiting.
