God's intent is not only to make us a member of His Kingdom and to make a great nation out of the family of God, but it's also God's intention to empower us to prosper. It's His will for us to prosper.
Gen 12:2 "And I will make of thee a great nation, and I will bless thee, and make thy name great: and thou shalt be a blessing."
God said to Abraham, "I'll make your name great, and you shall be a blessing." In other words, God said, "not only will I empower you to prosper, but you'll be so blessed that you'll be able to empower others to prosper."
Deuteronomy 28 not only lists the blessings for obedience in verses 1-14, it also lists the curses that come upon the disobedient.
Galatians 3 says Christ came to redeem you from the curse.
Thank God, we have been redeemed from the curse, but we have not been redeemed from the blessings!
After reading what the blessings are, it is very easy to see that the will of God is to empower us to prosper. God wants to empower us to prosper.
So we know that the blessing began before the Law and continued through the Law. The Word of God tells us that we have a better covenant, established upon better promises in Hebrews 8:6, Jesus is the surety of the new covenant with its better blessings.
Jesus did a miraculous thing in His life. He was born in the earth. Then He died and defeated the devil for you. He brought in a new and better covenant for His people! Three days later He was raised from the dead. He put you in His will and then came back from the dead to make sure you got all that was named for you in the better covenant. In other words, Jesus made sure that the blessings of the old covenant, or Old Testament, are maintained in your life. The curses were done away with. The blessings are yours to keep along with the blessings of the new and better covenant. It is God's will that you be empowered to prosper, and to seal this deal, He gave you Jesus as a guarantee that you would get and maintain all that the Old Testament promised and much more in the new. He has empowered you to prosper.
