“For all the promises of God in Him are Yes, and in Him Amen, to the glory of God through us”
Another way of saying it is: “For no matter how many promises God has made, they are “Yes” in Christ. And so through Him, the “Amen” is spoken by us to the glory of God.” God had already prophesied that He was going to do something, but still Daniel prayed.
Daniel could have just leaned back, put his feet up, and said, “Well, God, since You prophesied You’re going to do it, there’s no need for me to pray about it.” But he didn’t.
It’s a strange thing—the Bible teaches us to pray about what God has already promised He would do.
Even when God says He’s going to do something, He does it through the prayers of His people. God wants us to have a part in bringing about His will upon this earth through prayer.
