Chapter 3 — Lord's Day 3

Section 6. Q. 6: Did God create people so wicked and perverse? A. No. God created them good and in his own image, that is, in true righteousness and holiness, so that they might truly know God their creator, love him with all their heart, and live with God in eternal happiness, to praise and glorify him.
