All the tools in the world are of no use unless God ordains to open the ears to be able to hear. The gospel is foolishness to those that are perishing
1Cr 2:14 But the natural man receiveth not the things of the Spirit of God: for they are foolishness unto him: neither can he know [them], because they are spiritually discerned.
That has certainly been my experience in recent days. :O)
