The third primary way that God motivates us is by laying before us the blessings and rewards of obeying him. This is not like the health-wealth-prosperity gospel that allures people to Christ with the promise of earthly reward. Rather it is the guarantee for those who deny themselves, forego worldly pleasures, and even suffer that there will indeed be a reward.
This motivation is seen in Moses. Hebrews 11:24-26 tells us,
By faith Moses, when he was grown up, refused to be called the son of Pharaoh’s daughter, choosing rather to be mistreated with the people of God than to enjoy the fleeting pleasures of sin. He considered the reproach of Christ greater wealth than the treasures of Egypt, for he was looking to the reward.
Moses walked by faith amidst the pleasure of sin in Egypt because his reward wasn’t in Egypt. He was looking forward to a lasting reward with God.
As Christians we want to keep this awareness ever before us and before one another. There is great reward, blessing and pleasure in living in covenant obedience with our God. We are not to be indifferent to it. We are told to maximize it at all costs. We are told by Jesus to lay up for ourselves treasures in heaven (Matt. 6:20). Peter instructs us to set our hope fully on the grace that will be brought to us at the revelation of Jesus Christ (1 Pet. 1:13).
John Piper harps on this motivation more than any other writer I know. It comes out in all of his books, and it forms the theme of his book, Future Grace. Piper writes, “Loving your enemy doesn’t earn you the reward of heaven. Treasuring the reward of heaven empowers you to love your enemy.” 
The reality of eternal blessing is designed by God to move us towards the things of God. Who might you remind today of lasting pleasures in faith-filled obedience?
