In Exodus 24:12-16, God summoned Moses to the mountain to receive the law & commandments. Its interesting to note that Moses waited six days before God finally spoke to him on the seventh day. Remember, Moses was there because God summoned him. But God did not speak right away. Moses had to wait.
God summons us to come to him regularly to commune with him in prayer and in the Word. How many seconds pass by before we get impatient because God has not spoken to us? How long do we wait upon the Lord before rushing out into the busyness of our day? After all, we have places to go, people to see, things to do. Its not like we have the spare time of Moses, is it? All he had to do was lead a nation into the Promised Land while introducing them to Jehovah God as they fought the enemies along the way who would eliminate them from the face of the earth. Oh yeah, and he also had to deal with that 'grocery procurement' issue.
Now that I think about it, perhaps we should learn to wait upon the Lord. There are people you and I need to introduce to God. There are people in our lives we hope to lead into the Promised Land. There are enemies who would destroy us. And didn't Jesus say something about "our daily bread"?
May the Lord remind us daily that we are privileged to be summoned into his presence and that he is most certainly worth the wait.
