Luke 17: (tells you what is not seen of spirit working in man who looks and trying to see through flesh and blood)
20And when he was demanded of the Pharisees, when the kingdom of God should come, he answered them and said, The kingdom of God cometh not with observation:
21Neither shall they say, Lo here! or, lo there! for, behold, the kingdom of God is within you.
Romans 2:
28For he is not a Jew, which is one outwardly; neither
is that circumcision, which is outward in the flesh:
29But he
is a Jew, which is one inwardly; and circumcision
is that of the heart, in the spirit,
and not in the letter; whose praise
is not of men, but of God.
Paul also called man is temple so the Rev was John in spirit at the temple in us, Paul was Saul who was blind of spirit inside him, Paul revealed what happen inside us, smart of flesh and blood following OT as secular history that is milk gospel outside, meat is in you Gal 1:
11But I certify you, brethren, that the gospel which was preached of me is not after man.
12For I neither received it of man, neither was I taught
it, but by the revelation of Jesus Christ.
2Cor 13:
5Examine yourselves, whether ye be in the faith; prove your own selves. Know ye not your own selves, how that Jesus Christ is in you, except ye be reprobates?
6But I trust that ye shall know that we are not reprobates.
Rev 22:
16I Jesus have sent mine angel to testify unto you these things in the churches. I am the root and the offspring of David,
and the bright and morning star.
Flesh and blood looks for spiritual they never understand until your wakened.
