There is the amazing and yet understandable side of Moses that desired a closer relationship with God. He had communion with Him in a way that was described as "the Lord spoke to Moses face to face, as a man speaks to his friend." (Exodus 33:11). What a joy that communion with God must have been for him. And yet, he desired more. He prayed in v. 13 "show me now Your way".
It is impossible to know all that Moses had in mind when he asked the question, "show me now Your way", but surely there are some lessons that can be drawn.
It is perfectly clear that Moses thought God had a "way" And that it was a way that he needed to not only know but follow. Jesus taught the same thing. John 14:6 "I am the way, the truth, and the life. No one comes to the Father except through me." What a bold statement! When Aquila and Priscilla took Apollos aside, we are told, they "explained to him the way of God more accurately" (Acts 18:26). That also shows us that God's way must be taught accurately; and that there is grave danger in following a way other than "God's way". Some in Acts 19:9 spoke "evil of the Way before the multitude." Surely there is a way! A way that Moses wanted to know. A way that God could show him.
It also seems clear, in the context of Exodus 33 and 34 that Moses was concerned about worship. At least, that was the result of seeing the Lord's glory, (Exodus 34:8). And if the Lord's way involved worship then, so it must today. Moses was not free to worship God in any way that he chose. He knew that. He wanted to know God's will in the matter. God has given us, in His revealed will, the kind of worship that He desires. Jesus told the woman at Jacob's well in John 4:24 "God is Spirit, and those who worship Him must worship in spirit and truth." Worshipping in spirit describes the attitude with which we are to worship. Worshipping in truth describes that which has been authorized by God's Word as the "Way" in which we are to worship. Remember Jesus words in John 17:17 "Sanctify them by Your truth. Your word is truth."
There are five items of worship given in the New Testament and for which we find authority in the New Testament for our worship today. There is first the preaching or teaching of God's word. Numerous examples could be given as well as the command to "Go into all the world and preach the Gospel to every creature" (Mark 16:15). Is preaching important? Listen to God's word: "For since in the wisdom of God, the world through wisdom did not know God, It pleased God through the foolishness of the message preached to save those who believe." (1 Cor.1:21). The second (second only in the manner in which we are presenting them) item is prayer. We are commanded to "pray without ceasing". Paul also commanded the church in Ephesus through the young preacher Timothy "that supplications, prayers, intercessions, and giving of thanks be made for all men."(1 Timothy 2: 1). And this was clearly given in the context of worship. The third is the Lord's Supper. It is clear from the message of Jesus that this was to be a regular practice. The command "this do in remembrance of me" indicates a regular observance of the Lord's Supper. The New Testament church met on the first day of the week (1 Cor. 16:1,2; Acts 20:7) for the observance of the Lord's Supper. Even secular historians record that weekly observance. The fourth is the giving of our means. 1 Corinthians 16:1, 2 shows the necessity of this. Exactly the same wording concerning the frequency is used here as in regards to the Lord's Supper. An argument could be made that contribution should be as frequent as the observance of the Lord's Supper or vice versa. And fifthly, singing. Notice the command found in Ephesians 5:18, 19: "And do not be drunk with wine, in which is dissipation; but be filled with the Spirit, speaking to one another in psalms and hymns and spiritual songs, singing and making melody in your heart to the Lord." The command is to sing and the command includes the instrument upon which the melody is to be made: the heart.
There is a way, a prescribed way, to worship. Moses sought that way. We, too, can seek His Way through the Scriptures. Let's worship as God has directed.
