Then why in the desert did Jesus say that “Man does not live on bread alone but on everyword from the Mouth of God.”
What are you suggesting?
Scriptures clearly state that some things will not be known to men until Jesus returns.
AND that the things we do know of God are reveal to us by God - alone. Not Church Doctors.
1Cr 2:9 But as it is written, Eye hath not seen, nor ear heard, neither have entered into the heart of man, the things which God hath prepared for them that love him.
10 But God hath revealed [them] unto us by his Spirit: for the Spirit searcheth all things, yea, the deep things of God.
11 For what man knoweth the things of a man, save the spirit of man which is in him? even so the things of God knoweth no man, but the Spirit of God.
12 Now we have received, not the spirit of the world, but the spirit which is of God; that we might know the things that are freely given to us of God.
Flesh and blood cannot reveal Spiritual things - only God can reveal these things to us.
Matthew 16:17 And Jesus said to him, "Blessed are you, Simon Barjona, because flesh and blood did not reveal this to you, but My Father who is in heaven.
Mat 11:25 At that time Jesus answered and said, I thank thee, O Father, Lord of heaven and earth, because thou hast hid these things from the wise and prudent, and hast revealed them unto babes.
Men cannot explain the Gospel to men unless God opens their minds to understand.
Jhn 6:45 It is written in the prophets, And
they shall be all taught of God. Every man therefore that hath heard, and hath learned of the Father, cometh unto me.
