1st Samuel 15:22 And Samuel said, Hath the Lord as great delight in burnt offerings and sacrifices, as in obeying the voice of the Lord? Behold, to obey is better than sacrifice, and to hearken than the fat of rams.
[Patriarchs & Prophets pp 634] At Gilgal, Saul had made an appearance of great conscientiousness, as he stood before the army of Israel offering up a sacrifice to God. But his piety was not genuine. A religious service performed in direct opposition to the command of God only served to weaken Saul's hands, placing him beyond the help that God was so willing to grant him. In his expedition against Amalek, Saul thought he had done all that was essential of that which the Lord had commanded him; but the Lord was not pleased with partial obedience, nor willing to pass over what had been neglected through so plausible a motive.
God has given men no liberty to depart from His requirements. The Lord had declared to Israel, “Ye shall not do ... every man whatsoever is right in his own eyes;” but ye shall “observe and hear all these words which I command thee.” Deuteronomy 12:8, 28. In deciding upon any course of action we are not to ask whether we can see that harm will result from it, but whether it is in keeping with the will of God. “There is a way which seemeth right unto a man; but the end thereof are the ways of death.” Proverbs 14:12.
“To obey is better than sacrifice.” The sacrificial offerings were in themselves of no value in the sight of God. They were designed to express on the part of the offerer penitence for sin and faith in Christ and to pledge future obedience to the law of God. But without penitence, faith, and an obedient heart, the offerings were worthless.
Isaiah 1:19 If ye be willing and obedient, ye shall eat the good of the land: 20 But if ye refuse and rebel, ye shall be devoured with the sword: for the mouth of the Lord hath spoken it.
May God add His blessing to the study of His word. "Good night" and God bless!
