The Father's will is absolute and assured. He needs no reason for it because He is sovereign and all-knowing. The Father reveals Himself according to His will, as He decides. His Word proclaims His will. His Spirit of Truth (the Holy Ghost) gives power to His children.

The will of the flesh is what makes us our own god, "I am flesh". Our will of the flesh is linked to what we have brought into our body (and mind) through the 5 carnal sense gates. The carnal inputs influence and shape the carnal mind. Beware:

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

The born again guard the sensory gates with the Word (part of the Spirit) like a filter to avoid the vulnerabilities of our flesh but we still make mistakes. 

• 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.

To emphasize the fact Jesus knew the Spirit is incorruptible and eternal, and the flesh is temporal and decays, He said:

• And he said unto him, Why callest thou me good? there is none good but one, that is, God: but if thou wilt enter into life, keep the commandments. Matthew 19:17.
• And Jesus said unto him, Why callest thou me good? there is none good but one, that is, God. Mark 10:18; see also, Luke 18:19.

Remember, Jesus did not sin but said His flesh was not good, but only God (the Spirit) is good. 

Those of us who live in forgiveness of sin chose the will of God as the way to live forever as He promised. 

• And the world passeth away, and the lust thereof: but he that doeth the will of God abideth for ever. 1 John 2:17.

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!

• 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. 

Remain penitent and humble. 

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

Living in pursuit of the will of God should become our way (pattern) of life when we are born again. 

The master is Jesus. All of us who are born again comprise the body of Jesus the Christ as the children of God, now on earth. The term "body" is used in the context of a group of people alike in belief, acting in one accord and one mind (the Word of God and the mind of Christ).

No matter how we look, our lifestyles should reflect being born again of the Spirit because we are the light of the world and beacons in the groups and communities we are in. Some must repent and leave their current group because it isn't God's will they stay in, but the group from which they depart is an easy mission field. 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. 

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 purpose that He purposes in us, always in love. 

It's time for us to shine and help people find salvation or at least plant a seed for it.

• Yet if any man suffer as a Christian, let him not be ashamed; but let him glorify God on this behalf. For the time is come that judgment must begin at the house of God: and if it first begin at us, what shall the end be of them that obey not the gospel of God? And if the righteous scarcely be saved, where shall the ungodly and the sinner appear? Wherefore let them that suffer according to the will of God commit the keeping of their souls to him in well doing, as unto a faithful Creator. 1 Peter 4:16-19.

Jesus said "might" receive the promise because some will fall away and lose it all in the sea of Apostasy.

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

The will of man is a decision maker, by the faculty of decision, influenced by man's belief in whatever truth he adopts. 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, the person shall pursue God's will. If a person does not believe the Father's (God's) will is most important, the person shall pursue the will of the flesh.
