"Jesus Christ the same yesterday, and to day, and for ever." Hebrews 13:8.
This scripture confirms that God does not change. What He did before, He is still able to do today. We know what He will do today because we saw what He did yesterday. We know what He will do tomorrow because we are seeing what He is doing today. What He did in another person’s life is a revelation of what is possible in our own lives.
