In fact, the reason why all mankind became sinners, lived as servants of Satan, and even went to hell is because of the unbelief of our first ancestor, Adam. So, what are the concrete consequences of Adam’s unbelief? Knowing the results, we can see why Christ is so necessary for mankind.

God made Adam and gave him all the blessings. However, he commanded that you never eat the fruit of the tree that knows good and evil. He warned that on the day you eat it you will surely die. This may be a warning against the act of disobedience, but it can be said that our essence is with God and that we cannot live at all apart from God.

Gen 2:17 But of the tree of the knowledge of good and evil, thou shalt not eat of it: for in the day that thou eatest thereof thou shalt surely die.

Hos 6:7 describes the case of Adam as rebelling against God. In other words, Adam himself left God and rebelled.

Hos 6:7 But they like men have transgressed the covenant: there have they dealt treacherously against me.

In addition, Adam’s disobedience to God’s word also included denial of Christ, the Word of God. Man is made in the image of God, and the essential image of God is Christ. In other words, without Christ, humans are of no value like dust, but Adam did not know that and denied Christ, the word of God.

Rev 19:13 And he was clothed with a vesture dipped in blood: and his name is called The Word of God.

Of course, Satan is behind it. Satan tricked Eve and Adam to eat the fruit of good and evil. In particular, they were fooled by Satan’s lies about becoming like God. In fact, it is idolatry that humans are treated like God. When humans become God, they are actually the most cursed. Satan did. When Satan tried to become like God, he had no salvation and went to eternal hell. Humans do not have to be like God, but must be in God.

Gen 3:4 And the serpent said unto the woman, Ye shall not surely die: 5 For God doth know that in the day ye eat thereof, then your eyes shall be opened, and ye shall be as gods, knowing good and evil. 6 And when the woman saw that the tree was good for food, and that it was pleasant to the eyes, and a tree to be desired to make one wise, she took of the fruit thereof, and did eat, and gave also unto her husband with her; and he did eat. As a result of Adam’s disobedience, all mankind, descended from Adam, was also included in the sin, and death reigned to all mankind.

Rom 5:14 Nevertheless death reigned from Adam to Moses, even over them that had not sinned after the similitude of Adam’s transgression, who is the figure of him that was to come.

God did not leave Adam, but because of man’s sin, man could not be with the holy God.

Isa 59:2 But your iniquities have separated between you and your God, and your sins have hid his face from you, that he will not hear.

Now to humans, God is not the King, but Satan is the king. Man is a slave to Satan all his life and then goes to eternal hell.

Jn 8:44 Ye are of your father the devil, and the lusts of your father ye will do. He was a murderer from the beginning, and abode not in the truth, because there is no truth in him. When he speaketh a lie, he speaketh of his own: for he is a liar, and the father of it.

Rm 6:23 For the wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord.

Why did God send Christ to this earth? He sent Christ to this earth to solve the fundamental problems of man, namely, the problem of sin, slavery to Satan, and departure from God. God promised to send Christ immediately after Adam and Eve sinned.

Gen 3:15 And I will put enmity between thee and the woman, and between thy seed and her seed; it shall bruise thy head, and thou shalt bruise his heel.

Christ means the Anointed One. In the Old Testament, kings, prophets, and priests were anointed. To say that Jesus is the Christ means that Jesus is the true King, the true prophet, and the true priest. Jesus came to this earth as the true king and destroyed Satan’s work.

1 Jn 3:8 He that committeth sin is of the devil; for the devil sinneth from the beginning. For this purpose the Son of God was manifested, that he might destroy the works of the devil.

Jesus came to this earth as the true Priest and died on the cross to atone for our sins.

Heb 9:12 Neither by the blood of goats and calves, but by his own blood he entered in once into the holy place, having obtained eternal redemption for us.

As Jesus died on the cross, the veil of the temple was torn from top to bottom and the way to meet God through Jesus was opened.

Jn 14:6 Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me.
