Rom. 8:32 “He who did not spare His own Son, but delivered Him up for us all, how will He not also with Him freely give us all things?’”
All our spiritual blessing, capped by the great offering of God’s own son to redeem and reconcile us, is the great free gift of God. He gave all and does continually now give.
With all His giving, His grace also made us fit vessels for the receiving. “A man can receive nothing, unless it has been given him from heaven,” Jesus said. (Jn. 3:27)
With all that He gave, we often speak of our unworthiness to receive it. That is true in the sense of what we can ourselves call upon as an obligation or due owed by God, but it is not true in the sense that His gifts elevate us to rightful reception of His gifts, because this is what He wants fro us. So what is our only proper response? Humble reliving.
1 Cor. 4:7 For who regards you as superior? And what do you have that you did not receive? But if you did receive it, why do you boast as if you had not received it?”
The giving was of His grace. The receiving is only in what He has made us fit to be. So do we boast that we were lifted up enough to receive so much? No we humble receive and recognize His double grace, in giving so much and making us able to receive and make use of it.
