It may be foolishness to those who cant see it, but may we never get weary of telling those people the Gospel. For we know, that the Gospel is the power unto salvation to those who believe. Just as we were foolish, our eyes were opened by Salvation’s Grace. May we never give up on those who are blinded. God never gave up on us.

For the word of the cross is foolishness to those who are perishing, but to us who are being saved it is the power of God.
