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.Of course we know the ten plagues come next. One might sometimes wonder why it was Pharaoh didn't relent. It was pretty obvious God was at work; even his own magicians told him that (Ex 8:19). He did relent at times and agree to let them go worship, but as soon as the bad stuff stopped happening he went back to his previous decision.
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.
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.
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. And Pharaoh said, Behold, the people of the land now are many, and ye make them rest from their burdens.
And Pharaoh commanded the same day the taskmasters of the people, and their officers, saying, Ye shall no more give the people straw to make brick, as heretofore: let them go and gather straw for themselves. And the tale of the bricks, which they did make heretofore, ye shall lay upon them; ye shall not diminish ought thereof: for they be idle; therefore they cry, saying, Let us go and sacrifice to our God. Let there more work be laid upon the men, that they may labour therein; and let them not regard vain words.
So, for the pattern, we have a bad thing happen. A person decides to look to God. The bad thing goes away. The person decides to stop looking to God. Seem familiar? We too frequently only turn to God when we decide we need Him, when life has thrown a challenge at us we can't handle. Once we're back on level ground, we stop turning to God.
Granted, we have no plagues. And God does not appear to be using us specifically and individually to show His might to others. But that's really no reason to turn away when life gets good again. We're still used by God for His purposes and are still indebted to Him, for creating us first of all, and saving us.
