I find their exegetical arguments persuasive. Unfortunately, some people resist such an examination for they infer that this is motivated by a desire to give less, or at least will result in less giving in the church. The authors plead "not guilty" to the first charge, and even suggest that perhaps giving would increase if the arguments were more biblical.
They go on to survey the NT perspective on giving and suggest that our giving should be...
- Systematic: Give on a regular basis, that is, weekly, bi-monthly, monthly, etc. (1 Cor. 16:1).
- Proportional: Give as you have been prospered; according to your ability (1 Cor 16:2;
- 2 Cor 8:2–3)
- Sacrificial/generous: Give generously, even sacrificially, but not to the point of personal affliction (2 Cor 8:2–3;Phil 4:17–18)
- Intentional: Give deliberately in order to meet a genuine need, not out of guilt merely to soothe a pressing request (2 Cor 8:4; Phil 4:16)
- Properly motivated: Our motivation for giving should be love for others (2 Cor. 8:9), a desire for reciprocity (1 Cor 9:14–15; 2 Cor 8:12–14; cf. Gal 6:6), and an eye to the reward from God (2 Cor 9:6)
- Cheerful: God loves a cheerful giver (2 Cor 9:7)
- Voluntary: Giving ought to be done out of one’s free volition (2 Cor 8:2–3, 8; 9:7; Phil 4:18)
Craig Blomberg: “[t]he standard Paul exhorts us to follow is actually a more stringent one than the traditional tithe. If most affluent Western Christians were to be honest about the extent of their surplus, they would give considerably higher than 10% to Christian causes.”
Walter Kaiser: “if a tenth was the minimal amount under the Law, how can Christians do any less? Perhaps we should consider not how little but how much we can give, seeing how richly blessed we are in Christ.”
