Matthew 12:6 But I say unto you, That in this place is one greater than the temple. 7 But if ye had known what this means, I will have mercy, and not sacrifice, ye would not have condemned the guiltless. 8 For the Son of man is Lord even of the sabbath day.
The fact that Christ is above all law is the reason why in certain circumstances, He could instruct His people to do things, which might otherwise be unlawful according to the letter. When the Hebrews were about to leave Egyptian bondage, God told them to “Borrow” jewels of gold and silver from their neighbors. When God instructed Joshua and his men to march around Jericho for seven days, they doing so would of necessity include a Sabbath day, whichever day of the week one may have started on.
The Hebrews were all commanded to celebrate the Passover, as a memorial of God’s great deliverance from Egyptian bondage, yet when God commanded Elijah to hide at the brook Cherith, there’s no record that the prophet was required to, or did so, for at least three years. When Saul was commanded to take out Amalek, he did what might seem to some as the humane thing, in sparing that which he felt was good, and getting rid of all that was refuse.
The only problem is that it was not what God told him to do in this instance. Again, in another instance, a certain prophet by the name of Hosea is commanded by God to go marry a prostitute something that none of us as men should ever presume to do. Yet, when the command came from God Hosea was obligated to render obedience.
Hosea 1:2 The beginning of the word of the Lord by Hosea. And the Lord said to Hosea, Go, take unto thee a wife of whoredoms and children of whoredoms: for the land hath committed great whoredom, departing from the Lord. 3 So he went and took Gomer the daughter of Diblaim; which conceived, and bare him a son.
May God add His blessing to the study of His word. “Good night” and God bless!
