Excellent question setfree As I have said on many occasions there is almost nothing in the New testament that is not in the Old this is the forerunner (first) penecost.There is nothing new under the the sun what was before will be again Exodus of course is the story of God rescuing his people and leading them to the promised land This(Exodus) is a type of what he is doing in these end times if we follow him he will lead us to the promised land that is heaven on earth with Christ as King of Kings this is the 7th trump when he returns for his people, blessed are the overcomers.Exodus 19:19 "And when the voice of the trumpet sounded long, and waxed louder and louder, Moses spake, and God answered him by a voice."This is at mount Sinai, and God's People are here to hear God speak to them. This is the first Pentecost day, that will be remembered for all times in this earth age. Both this first Pentecost day, and the Pentecost day when the Holy Spirit came to indwell man, are reference points to another Pentecost day in the time of the end when all flesh on the face of the earth will hear the Spirit of God.Acts 2:19 "And I will shew wonders in heaven above, and sighs in the earth benearth; blood, and fire, and vapour of smoke:" [19] "The sun shall be turned into darkness, and the moon into blood, before that great and notable day of the Lord come:" [20]So what happens here? The seventh trump sounds and Jesus Christ returns to this earth. It is the false Christ that will be here when the cloven tongue is spoken through his elect,(mark 13) when they are put on trialAct 2:21 "And it shall come to pass, that whosoever shall call on the name of the Lord shall be saved.' "There only problem here is that most of the people at this end time will be following the wrong Christ, the false Christ Satan, as he sits in Jerusalem claiming himself to be God, with the world believing it. If you call on the wrong lord, you are with Satan. Jesus is the only name that a person can be saved by. You have to have the true doctrine of the Word, or you will chase after the false christ. Your doctrine should be the entire Word of God.Exodus 19:20 "And the Lord came down upon mount Sinai, on the top of the mount: and the Lord called Moses up to the top of the mount; and Moses went up."Here goes Moses back up on the mount to receive more of the Word from God. Moses went up the first trip to get the warning to get the people ready for the Pentecost, the seeing and hearing from God Himself. So this is Moses' second trip up the mountain.Exodus 19:21 "And the Lord said unto Moses, "Go down, charge the People, lest they break through unto the Lord to gave, and many of them perish."When Moses reached the top of the mount, God now told him to go back down and warn the people to stay away from the mount.Exodus 19:22 "And let the priests also, which come near to the Lord, sanctify themselves, lest the Lord break forth upon them." Get those priests and preachers to get their act together, and stop fooling around: Sanctify yourself, get yourself cleaned up also. If you are a reverend, you had better be right with and in God's Word, or you are in serious trouble before the Lord. God starts his judgment at the pulpit, with the priests and preachers.Exodus 19:23 "And Moses said unto the Lord, "The People cannot come up to mount Sinai: for Thou chargedst us, saying, `Set bounds about the mount, and sanctify it.' "Moses has been up the hill for the third time, and now he is getting a little upset with the Lord for making him go down again with the same message: "Sanctify yourself, get right before the Lord, get yourself cleaned up to face the Lord." Moses is an old man of over eighty years old, and the trips up the mountain must be wearing him out. You see God knows the people, and they get very lazy at times, and like to take their shortcuts. He know just how careless the people are in following His instructions. Just look around today.Most Christians have discarded the book of Revelation as to mixed up to understand, and many even think that the old testament is over and done with. This is a warning to us, just as it was a warning to the children of Israel camped at the foot of mount Sinai about to receive the Law and commandments of His People to follow. God was serious about warning the people of the danger coming upon not following His instructions.Exodus 19:24 "And the Lord said unto him, "Away, get thee down, and thou hast come up, thou, and Aaron with thee: but let not the priests and the people break through to come up unto the Lord, lest He break forth upon them." Moses wanted to sit and God is getting a little short with Moses; telling him to get down there and warn the People; and bring Aaron when you come up here again.Exodus 19:25 "So Moses went down unto the People, and spake unto them."Our Father always gives us a double witness, and several warning before the danger is allowed to happen. You can count on His Word. If you search the Scripture for the truth.
