For what if some did not believe? Shall their unbelief make the faith of God without effect?

You know when you first hear about the love of God and how that love was willing to redeem and restore the one who would be willing to receive that love.

Life change is that simple, to believe the love of God, enabling you to receive that love.  To receive the love of God expressed through the cross of calvary is more than mere words. 

It's shown through our obedience to His words, which produce life in us who believe.
