By faith Moses, when he had grown up, refused to be called the son of Pharaoh's daughter, choosing rather to endure ill-treatment with the people of God than to enjoy the passing pleasures of sin, (Hebrews 11:24, 25 NASB)
Moses had faith that God had something better for him. It's so easy to live for ourselves. Sometimes it is hard to honor God with our lives, but the reward is greater.
