Only Holy Spirit can put Truth in deep in our spirits . . . the Truth in nature is as an eye-opener or appetizer to begin the search for Truth and then the will to be submissive to that Truth. Conscience does not equal obedience, but is used by Satan to accuse and heap bonds of guilt on us. Only Truth empowered by Holy Spirit can penetrate the spirit and then we have a choice to turn towards or spurn.
- John 16:13 However, when he, the Spirit of truth, is come, he will guide you into all truth: for he shall not speak of himself; but whatever he shall hear, that shall he speak: and he will show you things to come.
