“Does not God bestow this wonderful deliverance from sin on the soul at conversion? Does He not sanctify and make it good and holy at the same time that He pardons its sins?’ No, I reply; although a great work is done for the soul at conversion, its deliverance from sin at that time is not complete. It is true, that He does a great deal for a man when He makes that remarkable change. He destroys the bondage in which sin holds the transgressor; but the destruction of sin out of the heart and out of the life is not entire.” (source)
“you not only possess the ability to live the kind of life that He desires, but that you actually do live it.” (source)
