Charles H. Spurgeon on Psalms 66:13

Burnt offerings. For ourselves, be we sure that the best sacrifice we can give to God is obedience; not a dead beast, but a living soul. The Lord takes not delight in the blood of brutish creatures. It is the mind, the life, the soul, the obedience, that he requires: 1Sa 15:22, "To obey is better than sacrifice." Let this be our burnt offering, our holocaust, a sanctified body and mind given up to the Lord, Ro 12:1-2. First, the heart: "My son, give me thy heart." Is not the heart enough? No, the hand also: Isa 1:16, Wash the hands from blood and pollution. Is not the hand enough? No, the foot also: "Remove thy foot from evil." Is not the foot enough? No, the lips also: "Guard the doors of thy mouth; " Ps 34:13, "Refrain thy tongue from evil." Is not thy tongue enough? No, the ear also: "Let him that hath ears to hear, hear." Is not the ear enough? No, the eye also: "Let thine eyes be towards the Lord." Is not all this sufficient? No, give body and spirit: 1Co 6:20, "Ye are bought with a price: therefore glorify God in your body, and in your spirit, which are God's." When the eyes abhor lustful objects, the ear slanders, the foot erring paths, the hands wrong and violence, the tongue flattery and blasphemy, the heart pride and hypocrisy; this is thy holocaust, thy whole burnt offering.
