Why was it necessary for God to come down to this earth in the form of human being? He could have simply stayed in heaven, worshiped and honored by all the heavenly beings, rather than being mocked and ridiculed on this earth without visible glory and might and power. But even though he knew he would suffer many things, he came down to this earth in the name of Christ Jesus 2000 years ago.
John 3: 16 16 For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life.
1 Timothy 6:15 which God will bring about in his own time—God, the blessed and only Ruler, the King of kings and Lord of lords, 16 who alone is immortal and who lives in unapproachable light, whom no one has seen or can see. To him be honor and might forever. Amen.
To receive eternal life we must meet God, but nobody can go up to heaven alive to meet God and receive eternal life. Since we cannot do anything to have eternal life with our own method, it was necessary for God to come down to this earth among human beings as one of them to give them eternal life. Then couldn’t he come down in his full glory and power, rather than coming as man in the flesh? He could and he did in the time of Moses. He appeared with the glory of God among his chosen people, but this time his people shunned him and refused to get near him because they were afraid. That is why God set up Moses as a mediator to teach his people of the way of eternal life and gave them the old covenant. But people did not obey the covenant because they just saw Moses, a mere man like one of them and rebelled against him without thinking he was working for the Almighty God. Because of the disobedience many died in the desert and could not enter into the rest prepared for them in the land of Canaan.
That is why God decided to come down to this earth as man in the flesh just like one of them so that he could live among his people and teach them the way of eternal life. This time he wanted to teach his people not through a mediator, but he himself wanted to teach them. So instead of sending a man as mediator, he himself came as mediator in human form and gave his people the new covenant so that they can receive eternal life.
Hebrews 9:15 For this reason Christ is the mediator of a new covenant, that those who are called may receive the promised eternal inheritance—now that he has died as a ransom to set them free from the sins committed under the first covenant.
