Requirements to know TRUTH

Requirements to know TRUTH
(Word of God)

Intent comes before content

1. Spiritual life

John 6:63 NASB
It is the Spirit who gives life; the flesh profits nothing; the words that I have spoken to you are spirit and are life.

2. Intent, desire, will

John 7:17 NASB
If anyone is willing to do His will, he will know of the teaching, whether it is of God or whether I speak from Myself.

3. Help in the Holy Spirit -

2 Peter 1:20-21 NASB
But know this first of all, that no prophecy of Scripture is a matter of one's own interpretation, for no prophecy was ever made by an act of human will, but men moved by the Holy Spirit spoke from God.

Revelation vs Rationalisation

1 Corinthians 2:9-12 NASB
but just as it is written, "T hings which eye has not seen and ear has not heard , A nd  which  have not entered the heart of man , All that God has prepared for those who love Him ." 
For to us God REVEALED them through the Spirit; for the Spirit searches all things, even the depths of God. For who among men KNOWS the thoughts of a man except the spirit of the man which is in him? Even so the thoughts of God no one KNOWS except the Spirit of God. Now we have received, not the spirit of the world, but the Spirit who is from God, so that we may KNOW the things freely given to us by God,

Knowing is something to do with the heart
