If we are to believe God, there must be a revelation of God. If we are to believe and know the Truth, there must be a revelation of the Truth. Thus, rather than ask God for faith. We ought to ask Him for revelation of the Truth. Then we will have something TO believe.
Paul writes, “Faith comes (to be) by hearing, and hearing comes by the Word of God.” (Rom. 10:17) He is not saying that God acts upon us and causes us to hear. Rather, He is saying that unless God speaks a Word – or gives a revelation – there is nothing TO hear. But once God does speak, and we do hear – the meaning of which is to embrace – then faith comes to be in us.

God does not expect us to muster up faith from out of ourselves. He expects us to hear the Truth He reveals. And once faith comes to be in me through my hearing of the Truth, then my faith IS the evidence and substance IN ME of the very Truth I have heard. “Now faith is the substance of things hoped for, the evidence of things not seen”.Hebrews 11:1

Faith is not emotional – we cannot believe with our emotions. Neither is faith intellectual – we cannot believe merely with our brains. Faith is a relationship – it is a trust and reliance upon God, based on the revelation of Himself to me.
