The Old and New Testaments are full of examples of "miracles" whose sole purpose is to convince the Jews and the readers in physical and visible terms that God is God and that Jesus is God, or at least the Son of God (in the Jewish sense of the word).
So this "take it on faith only" and God-is-not-susceptible-to-proof-is a later-day development that contradicts everything that's in the Bible.
Which is the entire point of the observation, "Man is not the measure of God."
No but the biblical God obviously wanted man to understand him in human concepts and in human words.
Plus God is not "my" (or "their") God. He is One God expressing as three Persons eternally, universally
That is your God, betty boop. Jews and Muslims do not consider that their God.
I don't have to "take it on faith only" when the entire Creation is screaming, "God made me!!!" God gave four revelations: Holy Scripture, the Incarnation of Christ, the "Book of Nature" (i.e., the creation itself) and the Holy Spirit with us. You, dear kosta, act as if there were only one revelation — the one given in human language. And even that you have reduced to a dead doctrinal reading. Just so much language to be manipulated into supporting your own preconceptions regarding the fictionality of God, and the futility of the Christian religion. Or so it seems to me. Sigh....
