Charles H. Spurgeon on Psalms 100:5

Know ye what God is in himself, and what he is to you. Knowledge is the mother of devotion, and of all obedience; blind sacrifices will never please a seeing God. "Know" it, i.e. consider and apply it, and then you will be more close and constant, more inward and serious, in the worship of him. Let us know, then, these seven things concerning the Lord Jehovah, with whom we have to do in all the acts of religious worship.

1. That the Lord he is God, the only living and true God; that he is a being infinitely perfect, self-existent, and self-sufficient, and the fountain of all being.

2. That he is our Creator: It is he that hath made us, and not we ourselves. We do not, we could not make ourselves; it is God's prerogative to be his own cause; our being is derived and depending.

3. That therefore he is our rightful owner. The Masorites, by altering one letter in the Hebrew, read it, "He made us, and his we are, "or, "to him we belong." Put both the readings together, and we learn, that because God "made us, and not we ourselves, "therefore we are not our own but his.

4. That he is our sovereign Ruler. We are his people, or subjects, and he is our prince, our rector or governor, that gives laws to us as moral agents, and will call us to an account for what we do.

5. That he is our bountiful Benefactor;we are not only his sheep whom he is entitled to, but the sheep of his pasture, whom he takes care of.

6. That he is a God of infinite mercy and good (Ps 100:5); The Lord is good, and therefore doth good; his mercy his everlasting.

7. That he is a God of inviolable truth and faithfulness; His truth endureth to all generations, and no word of his shall fall to the ground as antiquated or revoked. Matthew Henry.
