WLC Q.2: How doth it appear that there is a God?
The very light of nature in man, and the works of God, declare plainly that there is a God; (Rom. 1:19–20, Ps. 19:1–3, Acts 17:28) but his word and Spirit only do sufficiently and effectually reveal him unto men for their salvation. (1 Cor. 2:9–10, 2 Tim. 3:15–17, Isa. 59:21)
