Charles H. Spurgeon on Psalms 10:3

"The covetous, whom the Lord abhorreth." Christ knew what he spake when he said, "No man can serve two masters." Matthew 6:24. Meaning God and the world, because each would have all. As the angel and the devil strove for the body of Moses (Jude 1:9), not who should have a part, but who should have the whole, so they strive still for our souls, who shall have all. Therefore, the apostle saith, "The love of this world is enmity to God (James 4:4), signifying such emulation between these two, that God cannot abide the world should have a part, and the world cannot abide that God should have a part. Therefore, the love of the world must needs be enmity to God, and therefore the lovers of the world must needs be enemies to God, and so no covetous man is God's servant, but God's enemy. For this cause covetousness is called idolatry (Ephesians 5:5), which is the most contrary sin to God, because as treason sets up another king in the king's place, so idolatry sets up another god in God's place. Henry Smith.
