"You may receive forgiveness -- if you have sufficiently forsaken sin."
"You may know the message of grace -- if you have experienced a sufficient degree of conviction of sin."
. . . But this was to put the cart before the horse and turn the message of the gospel on its head. For whenever we make the warrant to believe in Christ to any degree dependent upon our subjective condition, we distort it. Repentance, turning from sin, and degrees of conviction of sin do not constitute the grounds on which Christ is offered to us.
Neither conviction nor the forsaking of sin constitutes the warrant for the gospel offer. Christ himself is the warrant, since he is able to save all who come to him. He is offered without conditions. We are to go straight to him! It is not necessary to have any money in order to be able to buy Christ.
