It is a very clear principle of life that “you cannot give what you do not have”. It would have being impossible for the Lord to use Moses to request of Pharaoh to let Israel go to serve Him, if Moses himself had not experienced that freedom in Christ. If Moses still had desired to be Pharaoh or to enjoy the flesh pots of Egypt or to enjoy the pleasures of sin, he would not have being able to deliver the message. For this reason it is important not to get confused when religious leaders fail at teaching a separation from the world message. This happens because they, unlike Moses, have not experienced what they are hired to teach. True religious liberty can only be taught by those who have experienced freedom from worldliness.
Exodus5:1 And afterward Moses and Aaron went in, and told Pharaoh, Thus saith the LORD God of Israel, Let my people go, that they may hold a feast unto me in the wilderness.
5:2 And Pharaoh said, Who [is] the LORD, that I should obey his voice to let Israel go? I know not the LORD, neither will I let Israel go.
5:3 And they said, The God of the Hebrews hath met with us: let us go, we pray thee, three days' journey into the desert, and sacrifice unto the LORD our God; lest he fall upon us with pestilence, or with the sword.
5:4 And the king of Egypt said unto them, Wherefore do ye, Moses and Aaron, let the people from their works? get you unto your burdens.
5:5 And Pharaoh said, Behold, the people of the land now [are] many, and ye make them rest from their burdens.
Why is it important at times for the Lord to rebuke state (king) for His saints’ sake?
Exodus 9:13And the LORD said unto Moses, Rise up early in the morning, and stand before Pharaoh, and say unto him, Thus saith the LORD God of the Hebrews, Let my people go, that they may serve me.
