Mark 11:22, Jesus said have faith in God. He was directing his remarks to Peter, who has already been born again. The natural man will not have faith in spiritual things that he cannot discern, 1 Cor 2:14.
if cannot discern fleshly one why Jesus said to Nicodemus about spiritual ?
and in the proverbs used to explain spiritual to non spiritual ?
just here's needed the language of spiritual things to understand beforehand
spiritual spiritually understands - without explanation - that is not about natural but spiritual ones
to the fleshly ones - in proverbs with explanation - to ones who believes
to the non believers it is not possible to explain
it is three sort of people -
natural - without faith - man of soul - did not denied the soul of his
fleshly - with faith but living according flesh
spiritual - with faith and love living according to the spirit
