Moreover
In 2 Corintians 8-9, the apostle sums up the Christian doctrine of giving. It may be thus summarized:
(1) It is a "grace," that is, a disposition created by the Spirit. (2 Corinthians 8:7).
(2) In contrast with the law, which imposed giving as a divine requirement, Christian giving is voluntary, and a test of sincerity and love. (2 Corinthians 8:8-12); (2 Corinthians 9:1); (2 Corinthians 9:2); (2 Corinthians 9:5); (2 Corinthians 9:7).
(3) The privilege is universal, belonging, according to ability, to rich and poor. (2 Corinthians 8:1-3); (2 Corinthians 8:12-15); (1 Corinthians 16:1); (1 Corinthians 16:2).
(4) Giving is to be proportioned to income. (2 Corinthians 8:12-14); (1 Corinthians 16:2). The Old Testament proportion was the tithe, a proportion which antedates the law. (Genesis 14:20).
(5) The rewards of Christian giving are:
(a) joy. (2 Corinthians 8:2).
(b) increased ability to give in proportion to that which has been already given. (2 Corinthians 9:7-11).
(c) increased thankfulness to God. (2 Corinthians 9:12).
(d) God and the Gospel glorified. (2 Corinthians 9:13); (2 Corinthians 9:14).
