The choice is yours: You can be like Esau, who sacrificed his birthright for a bowl of stew; and God hated him for that. And like Demas, who loved the present world more than what God had for him. Or you can be like Moses, who could possibly have become the next Pharaoh of Egypt (or at least a highly ranking individual in Egypt); but gave that up for a bright future with God.
Having this future may cost you in the present. It sure cost Moses!
