I think the best Scripture description for experiential knowledge is Ephesians 3:19 Amplified. It says, “(That you may really come) to know (practically, through experience for yourselves) the love of Christ, which far surpasses mere knowledge (without experience); that you may be filled (through all your being) unto all the fullness of God (may have the richest measure of the divine Presence, and become a body wholly filled and flooded with God Himself)!”

It is beyond just common knowledge that anyone can read about. It is the personal experience of interfacing with the truths of God’s word that describe His Person. 2 Timothy 2:13 says about God, “…He remains faithful; He cannot deny Himself.”

He backs His words with Himself, Who is the Living Word that cannot be changed or altered. He is the word that will not return void. He will accomplish what He has said He will do. He always fulfills His part ~ our part is simply to believe and immerse our life into His.
