Ha! Yes, many boneheads and pew warmers out there, lol. It did NOT "work" for me 20 years ago but, back then, I did not BELIEVE His grace was sufficient for my particular, sin.
I did not BELIEVE what certain boneheads were telling me.
Fast forward not too many years back, it is all different now, I can only say that when I opened my tight fist and just begged Him to take from me what I did not trust Him with, my eyes WERE opened. I kept walking around saying, to myself no less, "I see now" I see"! And that went on for many days and still comes into my head. God's grace IS sufficient for ANYTHING as He has proven it from that day on...for myself. He is a rewarder to those who DILIGENTLY seek Him. And, oh how true that is. Different with most as, we are individuals and our experiences are different...He want's fellowship with us...
