The Father is sovereign. His will is absolute. Only He defines the pathway to heaven, because His will shall be done on earth and in heaven.

Exactly, and only three wills are mentioned explicitly in the New Testament of the Word of God. All theoretical and theological discussions of the will that exist in the world must align with the following verse; otherwise, they are non-scriptural, and the stuff man and his religion made up.

The three wills are:

• ...Which were born, not of blood, nor of the will of the flesh, nor of the will of man, but of God. John 1:13. (Italics added).

We should understand and consider each of the three wills. They are:

1. The will of God.
2. The will of man that controls the eternal destination of his/her own soul by their own choice.
3. The will of the flesh and the desires of it lead us away from the will of God and toward sin.

(Note: The will of God is not directly stated in the verse above, but everyone should have no problem admitting there is a will of God. For example, the New Testament of the King James Bible uses the phrase "will of God" 23 times, "will of the Father" once, and "will of Him that sent me" (said Jesus) 3 times.)

By man's definition, human "will" can be determined.

God's will is different from man's will. Our Father's will is absolute and assured. He does not need to reason because He knows all. He set all things in motion from the beginning. His will IS prophecy.

It's all important! If you want to live forever as part of the true Royal Family in heaven, co-own the universe, and avoid a second death in hell among other things, the will of God tells us and proves the only way to do that is through Jesus the Christ-the Word of God. 

Jesus said:  

• For whosoever shall do the will of my Father which is in heaven, the same is my brother, and sister, and mother. Matthew 12:50.
• For whosoever shall do the will of God, the same is my brother, and my sister, and mother. Mark 3:35.
• And this is the will of him that sent me, that every one which seeth the Son, and believeth on him, may have everlasting life: and I will raise him up at the last day. John 6:40.

Like every creature, the will of the flesh is what makes the creature (including man) its own god: "I am [self-identified]." Our will of the flesh IS the desires and lusts of the natural body and carnal mind. From the reference of people who are born again and saved, God said it this way:

• Wherein in time past ye walked according to the course of this world, according to the prince of the power of the air, the spirit that now worketh in the children of disobedience: Among whom also we all had our conversation in times past in the lusts of our flesh, fulfilling the desires of the flesh and of the mind; and were by nature the children of wrath, even as others. Ephesians 2:2-3.

Those desires and lusts are shaped and augmented (expanded) by what we bring into our body (and mind) through the 5 carnal sense gates (taste, touch, sight, smell, and hearing). The carnal inputs influence and shape the carnal mind, but beware:

• For to be carnally minded is death; but to be spiritually minded is life and peace. Romans 8:6.

Being born again through repentance from sin is part of our claim to salvation through faith, even though our natural bodies may remain tempted. 

• Let no man say when he is tempted, I am tempted of God: for God cannot be tempted with evil, neither tempteth he any man: But every man is tempted, when he is drawn away of his own lust, and enticed. Then when lust hath conceived, it bringeth forth sin: and sin, when it is finished, bringeth forth death. James 1:13-15.

The born again learn to guard their sensory gates with the Word as a filter to avoid the vulnerabilities of our flesh and mind and yet we still make mistakes. To emphasize the fact that Jesus knew the Spirit is incorruptible and eternal, and the flesh is temporal and decays, He said:

• ...Why callest thou me good? there is none good but one, that is, God. Mark 10:18; see also Matthew 19:17 and Luke 18:19.

Why did Jesus say His flesh was not good? Like every person, He had a will of the flesh prone to sin, even though He didn't sin. He knew who He was. He knew His spirit (truth in Him) IS the Word of God, the Holy Spirit. When we are born again, we must know who we are. Our spirit (truth in us) receives the same Spirit (the Word of God) that Jesus has. We live in the Spirit (truth of God), continually by doing the will of God, starting with learning the Word of God. This is another reason why changing the Word of God to suit mankind is a bad idea.

Those of us who live in forgiveness of sin chose repentance from sin according to the will of God as the ONLY way to live forever as He promised. This is the starting point of doing God's will for everyone.

• And the world passeth away, and the lust thereof: but he that doeth the will of God abideth for ever. 1 John 2:17.
• I tell you, Nay: but, except ye repent, ye shall all likewise perish. Luke 13:3 and 5.

Jesus said:

• If any man will do his will, he shall know of the doctrine, whether it be of God, or whether I speak of myself. John 7:17. (Emphasis added).

We were given the Spirit of eternal life just as Jesus said we would. He also said we live forever with Him in the house of our Father, the universe of His will, always in love, because He is God and God is love! (Yes, a good way to contemplate the enormity of God is to consider the universe we know of in space as His will!)

Remain penitent, humble, and patient. God is not ignoring you.

• For ye have need of patience, that, after ye have done the will of God, ye might receive the promise. Hebrews 10:36.

Like baking the perfect cake, it takes the right ingredients and the right time. He will make you into the perfect creation. Thus, we come to the Lord as we are. The Spirit will grow the change in us from the inside out according to the Father's will as His purpose that He purposes in us, always in love.

For the born again, living in pursuit of the will of God becomes our way (pattern) of life. The Bible calls it "walking in the Spirit."

• There is therefore now no condemnation to them which are in Christ Jesus, who walk not after the flesh, but after the Spirit. Romans 8:1.
• This I say then, Walk in the Spirit, and ye shall not fulfil the lust of the flesh. Galatians 5:16; see also Ephesians 2:2 above.
• If we live in the Spirit, let us also walk in the Spirit. Galatians 5:25.

For example, we are the light of the world and beacons in the groups and communities we are part of. 

• As long as I am in the world, I am the light of the world. John 9:5.
• Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven. Matthew 5:16.

Some of us must repent and leave our current group because it isn't God's will to stay in it, but the group they leave becomes an easy mission field. After all, who knows more about where you came from and the sin you left than you? Be willing to help others find their way out of the darkness you were once in with them. 

The will of man is the gatekeeper of his greatest possession, his own soul. 

• For what is a man profited, if he shall gain the whole world, and lose his own soul? or what shall a man give in exchange for his soul? Matthew 16:26.
• For what shall it profit a man, if he shall gain the whole world, and lose his own soul? Mark 8:36.
• In your patience possess ye your souls. Luke 21:19.

You must come to know that the "will of man" has ONLY one choice to make: live forever by the "will of God" or die forever by the "will of the flesh". Thus, your will of man is a decision-maker, a faculty of decision influenced by your belief in whatever truth you adopt as your spirit of man.

Thus, the spirit of man (the truth in him) influences man's governance of his eternal soul because a man will always choose what he believes. If a person believes God's will is most important, they shall choose His will and the path of eternal life, beginning with the Word. Conversely, if a person does not believe the Father's (God's) will is most important, that person shall choose a path directed by their own will of the flesh and find an eternal second death in hell after their body dies.
