Do you realize that if one is not first converted and then achieve live individual communion with the Spirit of Jesus/Spirit of Truth/Spirit of Intercession/Spirit of Love through one's own heart/spirit, one cannot know or believe from one's heart that Jesus rose from the dead:
Romans: 10 KJV N.T.
9 that if you confess with your mouth the Lord Jesus and believe in your heart that God has raised Him from the dead, you will be saved.
The billion strong traditional Christians who parrot the above revelation do not seem to realize that one cannot believe anything in one's heart if one is not converted. 'To be converted' is a very precise passage or transformation that is clearly mentioned in the KJV N.T.
Being converted is directly linked to the instruction: seek ye first the kingdom of God within then all things will be added;
Matthew: 6 King James Version (KJV)
33 But seek ye first the kingdom of God, and his righteousness; and all these things shall be added unto you.
The above is seeking through a heart or spirit that is not 'waxed gross'.
One must be converted first before one can believe anything in one's heart. Traditional Christians do not know that they have to be converted, before they even seek Jesus.
Matthew: 18 KJV N.T.
3 And said, Verily I say unto you, Except ye be converted, and become as little children, ye shall not enter into the kingdom of heaven
Matthews: 13 KJV N.T.
15 For this people's heart is waxed gross, and their ears are dull of hearing, and their eyes they have closed; lest at any time they should see with their eyes and hear with their ears, and should understand with their heart, and should be converted, and I should heal them.
Notice that one must be converted first, then Jesus can heal one.
To be converted is to cease having a waxed gross (covered over) heart or spirit. This is to enable one to function through one's heart/spirit.
Then one can look to things that are not seen' and temporal. This enables one to believe things from one's heart. This also enables one to discern things in one's heart/spirit.
This enables one to search one's own heart to discern the Spirit of Jesus, within one's own heart or spirit. This is how one knows that Jesus rose to spirit heaven. Then, when on is led into all of one's works by precisely what this Spirit has in mind for one to know, pray for, say and do, one is healed/saved and delivered, by Jesus.
However before one can even believe anything from one's heart one must be awaken to/aware of, one's heart . . . one must be converted. Peter was not converted.
Jesus turned to Peter and said, Satan get thee behind me because Peter savorest the things of man and not the things of God. One who savorest the things of man is a person in the flesh. A natural man. He/she is not spiritually aware. Such a person's heart is waxed gross. Such a person's ears are dull of hearing, and his/her eyes he/she has closed.
Peter was in need of being converted. This is what identified him to be Satan. In that state Peter could not look to things of God. Things of God are not seen and temporal, (like the 'not seen' and eternal Spirit of Jesus).
Of course we all know that Paul was converted (he could discern spiritual things). And not only did Paul look to things that are 'not seen' and eternal, Paul had live communion with the Spirit, 'not seen' and eternal, Son of God, Lord Jesus. He was spiritually functional.
Up to the very last, Peter and those others, needed physical signs to know that Jesus rose to spirit heaven. They were not converted. Therefore they were not spiritually functional. They needed physical signs for events that were purely spiritually. This is why Jesus had to show himself physically rising to a cloud beyond their sight.
Fact is, Jesus rose to spirit heaven clad only in His 'not seen' and eternal, spiritual body. Even up to that point, Peter continue to savorest the things of man. He remained a child of the flesh. He was not converted and this prevented him from discerning the Spirit, 'not seen' and eternal, Son of God, Lord Jesus (as Paul did, on the road to Damascus).
Of course Peter came away telling every one that Jesus rose to heaven is a physical body. And he is seated on the right side of God in a physical body. Fact is all that Peter saw was: Jesus, rising in a physical body, to a cloud beyond his sight. However Paul knew the truth:
1 Corinthians: 15 KJV N.T.
35 But some man will say, How are the dead raised up? and with what body do they come?
44 It is sown a natural body; it is raised a spiritual body. There is a natural body, and there is a spiritual body.
47 The first man is of the earth, earthy; the second man is the Lord from heaven.
