The three wills as taught in Scripture:
The Bible teaches us of three wills: The will of man, the will of Jesus, and the will of the Father. They are distinctly different.
Man’s Will: "1 The fool hath said in his heart, There is no God. Corrupt are they, and have done abominable iniquity: there is none that doeth good.
2 God looked down from heaven upon the children of men, to see if there were any that did understand, that did seek God.
3 Every one of them is gone back: they are altogether become filthy; there is none that doeth good, no, not one." - Psalm 53:1-3.
“10 As it is written, There is none righteous, no, not one:
11 There is none that understandeth, there is none that seeketh after God.
12 They are all gone out of the way, they are together become unprofitable; there is none that doeth good, no, not one." - Romans 3:10-12.
“7 Because the carnal mind is enmity against God: for it is not subject to the law of God, neither indeed can be.
8 So then they that are in the flesh cannot please God." - Romans 8:7-8.
Our wills are not free, but a slave to sin. The reference of taking of the water freely in Revelation 21:6 - “6 And he said unto me, ‘It is done. I am Alpha and Omega, the beginning and the end. I will give unto him that is athirst of the fountain of the water of life freely.'” is when the saints are already raptured incorruptible, in glory; not now, while still corruptible. We start out in the fleshly, carnal mind, not able to come to Christ of our own volition because Jesus says that none do. Period.
Jesus' Will: "The Lord is not slack concerning his promise, as some men count slackness; but is longsuffering to us-ward, not willing that any should perish, but that all should come to repentance." - 2 Peter 3:9.
Note that His promise is to us-ward (believers), not to all people, just the believers.
"And the angel said unto them, Fear not: for, behold, I bring you good tidings of great joy, which shall be to all people." - Luke 2:8.
“15 That whosoever believeth in him should not perish, but have everlasting life.
16 For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.
17 For God sent not his Son into the world to condemn the world; but that the world through him might be saved.” - John 3:15-17.
These verses are often confused with preaching free will, but they say nothing of will, free or otherwise. They teach salvation by belief. Whosoever believes shall be saved. Whosoever won't believe, won't be saved. These are facts, future tense, not speaking of our will as being in control. Jesus' will is to save the whole world.
The Father's Will: "38 For I came down from heaven, not to do mine own will, but the will of him that sent me.
39 And this is the Father’s will which hath sent me, that of all which he hath given me I should lose nothing, but should raise it up again at the last day.
40 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 6:38-40.
In John 17 Jesus prays to the Father, not for the world, but those whom the Father gives to Jesus out of the world, not only up to that time, but for all believers in the future as well (verses 20-21).
" 37 All that the Father giveth me shall come to me; and him that cometh to me I will in no wise cast out." - John 6:37.
"No man can come to me, except the Father which hath sent me draw him: and I will raise him up at the last day." - John 6:44.
"64 But there are some of you that believe not. For Jesus knew from the beginning who they were that believed not, and who should betray him.
65 And he said, ‘Therefore said I unto you, that no man can come unto me, except it were given unto him of my Father.’
66 From that time many of his disciples went back, and walked no more with him." - John 6:64-66.
"Jesus saith unto him, ‘I am the way, the truth, and the life: no man cometh unto the Father, but by me.’" - John 14:6.
So, we can't come to the Father but by the Son, and we can't come unto the Son except it be given to us of the Father; that He draws us to the Son, that He gives us to the Son, who will not cast us out for any reason and will raise us up at the last day. That all that the Father gives to Jesus shall come to Him. There is not even an inkling of man's responsibility or will involved here, neither indeed can be; it is all the work of God. Three wills, starting with the Father, completed by the Son with the Holy Spirit, and man who strives with God in this life, even after salvation.
