Thanks be to God for His indescribable gift! (9:15)
This simple concluding benediction is one of the richest statements in Scripture. God’s indescribable gift is, of course, His Son—the most magnanimous, glorious, wonderful gift ever given, the gift that inspires all other gifts.
For a child will be born to us, a son will be given to us; and the government will rest on His shoulders; and His name will be called Wonderful Counselor, Mighty God, Eternal Father, Prince of Peace. (Isa. 9:6)
“For God so loved the world, that He gave His only begotten Son, that whoever believes in Him shall not perish, but have eternal life. For God did not send the Son into the world to judge the world, but that the world might be saved through Him.” (John 3:16–17)
He who did not spare His own Son, but delivered Him over for us all, how will He not also with Him freely give us all things? (Rom. 8:32)
But when the fullness of the time came, God sent forth His Son, born of a woman, born under the Law. (Gal. 4:4)
By this the love of God was manifested in us, that God has sent His only begotten Son into the world so that we might live through Him. In this is love, not that we loved God, but that He loved us and sent His Son to be the propitiation for our sins. (1 John 4:9–10)
God’s gift of the Lord Jesus Christ is the basis for Christian giving. Jesus was the “grain of wheat [that] falls into the earth and dies, … but if it dies, it bears much fruit” (John 12:24). God, as it were, dies, it bears much fruit” (John 12:24). God, as it were, planted Him as a seed and reaped a harvest of redeemed people. Believers are called to “be imitators of God, as beloved children” (Eph. 5:1), and they are never more like Him than when they give.
Subsequent history reveals how the Corinthians responded to Paul’s plea in chapters 8 and 9 regarding the offering. Sometime after writing 2 Corinthians, Paul visited Corinth as he had planned (2 Cor. 12:14; 13:1–2). He remained there about three months (Acts 20:1–3), during which time he penned Romans. In that letter, Paul revealed that the Corinthians had responded positively concerning the collection:
Now, I am going to Jerusalem serving the saints. For Macedonia and Achaia have been pleased to make a contribution for the poor among the saints in Jerusalem. Yes, they were pleased to do so, and they are indebted to them. For if the Gentiles have shared in their spiritual things, they are indebted to minister to them also in material things. (Rom. 15:25–27)
Not only had they contributed, but “they were pleased to do so”; they were joyful, happy, cheerful givers. They were on the path to true prosperity.
