The LORD Descends upon the Mountain
The LORD tells Moses that He will come to him in a way that the people can see. In order to be present, the people must meet strict conditions. They must be holy, there must be nothing that does not befit the holiness of God. On the third day they shall see the LORD descending upon the mountain.
A respectful distance must be observed around the mountain. Anyone, human or animal, who touches the mountain while God appears on it, must be killed. The absolute holiness of God does not allow a living being, who is a sinner or connected to sin, to come into His presence. Only when a signal is given that is determined by Him, can the mountain be approached.
The people act in accordance with God’s precepts. Moses sanctifies the people and they make their clothes suitable for the presence of God. Three days they have to live like this, looking forward to that appearance. Sexual intercourse between man and woman is not allowed either during that time. Everything must be focused on the appearance of the LORD.
This does contain a lesson for us. Do we sanctify our lives with a view to our meeting with Him when He comes (1 John 3:3)? His coming is not the only thing. If we may call upon God as Father, the command is to be holy, as He is holy (1 Peter 1:15-Nehemiah :). Is it our desire to live a holy life because of our daily relationship with Him? Can we also omit the things that are lawful in themselves for a certain period of time in order to concentrate fully on Him and the search for His will during that particular period of time (cf. 1 Corinthians 7:5)?
There is a big difference in the motive of action between a member of God’s people then and a member of God’s people now. Israel is acting out of fear of retaliation. We may act out of love for the Father.
When the LORD appears to them, this happens with the occurrence of phenomena that cause fear and tremors. To this revelation of God, the people are brought by Moses. In Hebrews 12, the writer sets this approach to God with fear and trembling, approaching on the basis of the law. This is opposite to us approaching God through the work of the Lord Jesus which is now the position of the believer, approaching on the basis of grace. The contrast is enormous: “For you have not come to [a mountain] that can be touched and to a blazing fire, and to darkness and gloom and whirlwind, and to the blast of a trumpet and the sound of words which [sound was such that] those who heard begged that no further word be spoken to them. For they could not bear the command, “If even a beast touches the mountain, it will be stoned.” And so terrible was the sight, [that] Moses said, “I am full of fear and trembling.” But you have come to Mount Zion and to the city of the living God, the heavenly Jerusalem, and to myriads of angels, to the general assembly and church of the firstborn who are enrolled in heaven, and to God, the Judge of all, and to the spirits of [the] righteous made perfect, and to Jesus, the mediator of a new covenant, and to the sprinkled blood, which speaks better than [the blood] of Abel” (Hebrews 12:18-Jeremiah :).
