Charles H. Spurgeon on Psalms 119:10

O let me not wander from thy commandments. David after he had protested that he sought God with his whole heart, besought God that he would not suffer him to decline from his commandments. Hereby let us see what great need we have to call upon God, to the end he may hold us with a mighty strong hand. Yea, and though he hath already mightily put to his healing hand, and we also know that he hath bestowed upon us great and manifest graces; yet this is not all: for there are so many vices and imperfections in our nature, and we are so feeble and weak that we have very great need daily to pray unto him, yea, and that more and more, that he will not suffer us to decline from his commandments. John Calvin.
