The Scriptures that speak more powerfully about giving an offering in the New Testament are 2 Cor 8 and 9.
David J. MacLeod, in his article in The Emmaus Journal 6 (1997), titled “The Primacy of Scripture in the Church,” powerfully summarises the New Testament principles of giving an offering: Free will Giving is to be … • voluntary, not forced (2 Cor 8:3, 9:5-7) • generous, not parsimonious (2 Cor 8:2, 9:6,13) • enthusiastic, not grudging (2 Cor 8:4, 11-12, 9:7) • deliberate, not haphazard (2 Cor 9:7) • regular, not spasmodic (1 Cor 16:2) • proportionate, not arbitrary (1 Cor 16:2) • sensible, not reckless (2 Cor 8:11-12, I Cor 16:2) • unobtrusive, not ostentatious (Matt 6:1-4)
From the above it can be summarized that New Testament Offerings should meet the following criteria: should be systematic, regular, proportional to the level of God’s blessing, liberal and generous, cheerful and without coercion while trusting God to supply our needs.
This is going to be my offering policy from here onwards!
