John Chrysostom
See, he does not wish to increase their guilt, but rather teaches them to refer everything to God. The apostles knew that one should not be so concerned to say something worthy of God as to say what is useful to the hearers. Notice how covertly he also points to their guilt. If God did so much for them, then they deserve punishment for not knowing their Nourisher while enjoying such blessings. Yet he does not say this plainly, but only hints at it, saying, "giving us rains from heaven." So David also said, "They were enriched with the fruit of wheat, wine, and oil" (Ps 4:8). In many other places, when he speaks about creation, he points to this. Jeremiah likewise first speaks of creation, and then of providence, which appears in the sending of rains. Paul is guided by these things in his speech. "Filling," he says, "our hearts with food and gladness." Food is given in abundance, not only in sufficiency and according to need.
