24 ¶ Father, I will that they also, whom thou hast given me, be with me where I am; that they may behold my glory, which thou hast given me: for thou lovedst me before the foundation of the world. 25 O righteous Father, the world hath not known thee: but I have known thee, and these have known that thou hast sent me. 26 And I have declared unto them thy name, and will declare it: that the love wherewith thou hast loved me may be in them, and I in them.
The Father, the Son, and the Holy Ghost are one being with three parts. God’s love for Himself, His unity, is shared with us and is to be exemplified in how the church operates in the world, or at least it is meant to be that way. Christ’s will is that we be with Him and behold His glory. Before the creation God loved the Son, as He loves us now.
God, by His foreknowledge, saw who would receive Christ and chose them also before the foundation of the world.
1Peter 1:2 Elect according to the foreknowledge of God the Father...
Ephesians 1:3 ¶ Blessed be the God and Father of our Lord Jesus Christ, who hath blessed us with all spiritual blessings in heavenly places in Christ: 4 According as he hath chosen us in him before the foundation of the world, that we should be holy and without blame before him in love: 5 Having predestinated us unto the adoption of children by Jesus Christ to himself, according to the good pleasure of his will, 6 To the praise of the glory of his grace, wherein he hath made us accepted in the beloved.
Predestinated, once saved, to the adoption, our physical resurrection in a glorified body;
Romans 8:23 And not only they, but ourselves also, which have the firstfruits of the Spirit, even we ourselves groan within ourselves, waiting for the adoption, to wit, the redemption of our body.
The world does not know God. The world has created a version of God who is weak and distant, someone you call in times of trouble but who had no part in giving you that trouble. The God the world invented justifies their power structures, their social classes, their standards, their pride, their bigotry, and their violent expressions of power. But the Son knows the Father as they are one being. Now the disciples know the Son came from the Father.
Christ has declared God the Father to the disciples so that they can manifest the love the Father has for them and for Christ to a fallen world, because Christ is in them. This is the key to being a Christian, the Bible teaches, to manifest Christ, and therefore God, to a lost world.
John 1:18 No man hath seen God at any time; the only begotten Son, which is in the bosom of the Father, he hath declared him.
Only Christ knows God the Father because He is one with God the Father. Only Christ reveals that knowledge to mankind. All others who claim to know God or to reveal God to man, whatever religious tradition they come from, are in error and do not reveal the God who created them. There is only one way of knowledge and salvation to God.John 14:6 Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me.
