And the Lord told Moses, "Go to the people and purify them today and tomorrow. They must wash their clothes and be prepared by the third day, for on the third day the Lord will come down on Mount Sinai in the sight of all the people.—Exodus 19:10–11

Meeting with God requires preparation. God is awesome and perfectly holy. Barging into His presence unprepared is an affront. When the children of Israel were to meet with Him, God commanded them first to take two full days to prepare. Once the people were ready, however, God spoke to them with thunder and lightning, with fire and smoke and the sound of loud trumpets (Exod. 19:16–25). It was through this encounter that God revealed such marvelous truths as the Ten Commandments, establishing the standard by which God expected His people to live.

You cannot spend day after day in the world without its affecting your mind and will and heart. It doesn't take long to become disoriented to the ways of God. The world has a dulling effect on your spiritual sensibilities. God established the Sabbath so His people could take an entire day to refocus on Him and His will for them after spending six days in the world.

How do you prepare for your times of worship? What fills your mind the night before? Often the last thing you put into your mind at night is still on your mind the next morning. Genuine worship requires spiritual preparation. Your experiences of worship reflect your spiritual preparation. Prepare yourself now for your next encounter with God.
