God is always doing something different. It is not a new thing, it is the next thing.
Romans 11:33, “O the depth of the riches and wisdom and knowledge of God! How unsearchable are His judgments and unfathomable are His ways!” Modern English Version
After God set up and sanctified the “tent of meeting” or tabernacle, Moses no longer went up on a mountain to hear from Him. He went to the “tent of meeting.”
Numbers 7:89, “And then Moses went into the tent of meeting to speak with Him, and he heard the voice of the One speaking to him from the mercy seat that was on the ark of the testimony, from between the two cherubim, and He spoke to him.” Modern English Version
I’m sure the children of Israel didn’t love the new way God set up for them to hear from Him. It was easy to wait for Moses to come down from the mountain and give them instructions.
But this new “tabernacle” cost them. They had to provide everything to build it. They had to provide animals, flour, and incense for the sacrifices. It would continue to cost them.
People like to go out into nature because they feel close to God there. They say they don’t “feel” God in church.
Going into nature doesn’t cost them. They don’t have to examine themselves. They don’t have to clean up. They don’t have anyone telling them to change their behavior to become more like Christ.
There were 2 more times God commanded Moses to climb a mountain: 1) Mount Pisgah, where God reprimanded him, (see Deuteronomy 3:27), and 2) Mount Nebo, where he died, (see Deuteronomy 32:49).
Going back to the old ways leads to reprimand and death. God planned for Moses to take the children of Israel into the land of Canaan. On Mount Pisgah, God showed him what He wanted to give him, but no longer could.
God has a specific plan for each life. We will not fulfill all He has planned for us if we disobey Him. We have to follow our leaders and do the next thing.
Hebrews 10:25, “Let us not forsake the assembling of ourselves together, as is the manner of some, but let us exhort one another, especially as you see the Day approaching.” Modern English Version
