That makes no sense at all.
ALL Scripture is useful for teaching and there are passages that indicate that all CAN approach Him if we accept His conditions.
Every person has been shown saving grace.
But no one will...that is the point...no one will accept His conditions because we are dead in sin and in reality hate God in our unregenerate state. So therefore we can never come to God UNLESS hHe draws us,,,in the Greek the word for the draw by God of the individual is literally the word DRAG. so man cannot come to Him on their own...God must initiate...coming to God is NOT synergistic in nature, where we cooperate, but is rather monergistic...where He predestines, chooses and hen draws the individual...
