4 which I commanded your fathers in the day that I brought them forth out of the land of Egypt, out of the iron furnace, saying, Obey my voice, and do them, according to all which I command you: so shall ye be my people, and I will be your God;

Matthew Henry's Commentary on Jeremiah 11:4

Commentary on Jeremiah 11:1-10

(Read Jeremiah 11:1-10)

God never promised to bestow blessings on his rational creatures, while they persist in wilful disobedience. Pardon and acceptance are promised freely to all believers; but no man can be saved who does not obey the command of God to repent, to believe in Christ, to separate from sin and the world, to choose self-denial and newness of life. In general, men will hearken to those who speak of doctrines, promises, and privileges; but when duties are mentioned, they will not bend their ear.
