Kay17:
Interesting to see how therapeutic Christianity can be to our restless bestial nature.

Does Christianity really change the bestial makeup of man? Can Christianity succeed to quieten man's ambitions or emotions or passions or impulses which often overcome his sense of reasoning and drive man to anger sin and all?

Both man and beasts are animals, in the parlance of Biology. What is the difference between man and beast? is it merely the genetic makeup? Does the Bible have an answer to this question. The Bible's answer to this question will help to address the issue raised in the comment quoted above. How therapeutic can Christianity be to man's restless bestial nature; man's ambitions or emotions or passions or impulses, which often overcome his sense of reasoning and drive man to anger, sin and all.

Ge. 2:7 The LORD God formed the man from the dust of the ground and breathed into his nostrils the breath of life, and the man became a living being.

Jn. 20:22 And with that he breathed on them and said, “Receive the Holy Spirit.

God formed man from the dust of the ground, just as He formed the beasts. But God did to man what He didn't do to the beasts, which is to breathe into man His Holy Spirit. the presence of the Holy Spirit in man turned man into an image of God, or a son of God. We know that breathing the Holy Spirit into man enraged one third of Gods's angels, who then rebelled against Him; that is by the way.

The Holy Spirit in man became the inner or spirit man. What is the purpose of this inner spirit man?

He. 2:8 (KJV) Thou hast put all things in subjection under his feet. For in that he put all in subjection under him, he left nothing that is not put under him. But now we see not yet all things put under him.

He. 2:8 (CEB) You put everything under their control. When he puts everything under their control, he doesn’t leave anything out of control. But right now, we don’t see everything under their control yet.

The purpose of the inner spirit man is control; control of the outer man and the world generally.

Ge. 3:6 When the woman saw that the fruit of the tree was good for food and pleasing to the eye, and also desirable for gaining wisdom, she took some and ate it. She also gave some to her husband, who was with her, and he ate it.
Ge. 3:7 Then the eyes of both of them were opened, and they realised that they were naked; so they sewed fig leaves together and made coverings for themselves.
Ge. 3:8 Then the man and his wife heard the sound of the LORD God as he was walking in the garden in the cool of the day, and they hid from the LORD God among the trees of the garden.
Ge. 3:9 But the LORD God called to the man, “Where are you?”
Ge. 3:10 He answered, “I heard you in the garden, and I was afraid because I was naked; so I hid.”

2Co. 5:1 Now we know that if the earthly tent we live in is destroyed, we have a building from God, an eternal house in heaven, not built by human hands.
2Co. 5:2 Meanwhile we groan, longing to be clothed with our heavenly dwelling,
2Co. 5:3 because when we are clothed, we will not be found naked.
2Co. 5:4 For while we are in this tent, we groan and are burdened, because we do not wish to be unclothed but to be clothed with our heavenly dwelling, so that what is mortal may be swallowed up by life.
2Co. 5:5 Now it is God who has made us for this very purpose and has given us the Spirit as a deposit, guaranteeing what is to come.

By eating the forbidden fruit, Adam and Eve grieved the Holy spirit that was in them. The Spirit left them and they became naked--zero control. They covered themselves with fig leaves, which could mean that they descended to the spiritual level of trees--lower than animals. God later clothed them with animal skin, which could mean that God raised mankind from the spiritual level of trees to the spiritual level of beasts. Satan later flooded man with evil spirits, by which he is able to control man.

1Cor. 14:32The spirits of prophets are subject to the control of prophets.

The Holy that God gives to His son is very powerful and is subject to control by the son of God. To the contrary, the spirit of Satan in a person manipulates the person and cannot be controlled by the person. However, Satan also gives his sons (witches and wizards) powerful spirits that they can control.

2Pe. 1:3 His divine power has given us everything we need for life and godliness through our knowledge of him who called us by his own glory and goodness.

Ph. 4:13 I can do everything through him who gives me strength.

The Spirit that God gives to His son is capable of giving the son of God everything that is needed for life and godliness. I want to focus on godliness here, because the Bible says that we should seek first the kingdom (or sonship) of God, which a person obtains when he receives the Holy Spirit, and the righteousness of God (godliness), so that every other thing we need will be given to us.

What causes ungodliness is the evil spirits that Satan uses to control mankind. Through the Holy Spirit, a son of God can drive out all evil spirits in him, and then through the Holy Spirit decree how his life should be. A son of God can control his body by the Holy Spirit.
