WLC Q.101: What is the preface to the ten commandments?
The preface to the ten commandments is contained in these words, I am the Lord thy God, which have brought thee out of the land of Egypt, out of the house of bondage. (Exod. 20:2) Wherein God manifesteth his sovereignty, as being JEHOVAH, the eternal, immutable, and almighty God; (Isa. 44:6) having his being in and of himself, (Exod. 3:14) and giving being to all his words (Exod. 6:3) and works: (Acts 17:24,28) and that he is a God in covenant, as with Israel of old, so with all his people; (Gen. 17:7, Rom. 3:29) who, as he brought them out of their bondage in Egypt, so he delivereth us from our spiritual thraldom; (Luke 1:74–75) and that therefore we are bound to take him for our God alone, and to keep all his commandments. (1 Pet. 1:15,17–18, Lev. 18:30,19:37)
