If we try to justify our belief by “understanding” God we then fall into the error of looking for a hidden, physical object, like a pebble hidden under a stone.
So, we ought not to try to jusify our belief by understanding God.
Instead, we should look to intuition and experience. What comes to us in intuition and experience is not hidden, and cannot be hidden.
If one has to justify belief, then his belief is in error. Because God need no justification, He is Just, in all that He says and does. Therefore the Justification of all who believe, and Trust in Him and His Word. But it is foolishness to disregard understanding God, because knowledge and understanding is of God, and He gives it to those who seek it, that they may give what they have received of God.
Jer:9:23: Thus saith the LORD, Let not the wise man glory in his wisdom, neither let the mighty man glory in his might, let not the rich man glory in his riches:
24: But let him that glorieth glory in this, that he understandeth and knoweth me, that I am the LORD which exercise lovingkindness, judgment, and righteousness, in the earth: for in these things I delight, saith the LORD.
Nothing that God has made, requires our approval, it is God who says what is good. And what He says is good for all that He has made.
