Charles H. Spurgeon on Psalms 119:140

Therefore thy servant loveth it. Love in God is the fountain of all his benefits extended to us; and love in man is the fountain of all our service and obedience to God. He loved us first to do us good; and hereof it comes that we have grace to love him next to do him service. Love is such a duty that the want thereof cannot be excused in any; for the poorest both may and should love God: yet without it all the rest thou canst do in his service is nothing; nay, not if thou shouldest give thy goods to the poor, and offer thy body to be burned. Small sacrifices, flowing from faith and love, are welcome to him, where greater without these are but abomination to him. Proofs of both we have in the widow's mite and Cain's rich oblation; whereof the one was rejected, the other received. Happy are we though we cannot say, "We have done as God commands, "if out of a good heart we can say, "We love to do what he commands." William Cowper.
