He comforts us by showing us sin. The comfort of God’s reproof lies in the fact that the very thing, which causes the conviction, is the righteousness that is given to take away the sin for which we are convicted.
“For as many as are led by the Spirit of God, these are the sons of God. For you did not received the spirit of bondage again to fear, but you have received the Spirit of adoption, by whom we cry out, “Abba, Father.” The Spirit Himself bears witness with our spirit that we are children of God” (Rom. 8:14-16). Ellet J. Waggoner
"These men had been with one mind persevering in prayer for this very object. They were also of that class mentioned in John 7:17; they had been, and were still, followers of Christ; so it was to be expected that they should know of the doctrine. And lastly, they had studied the word of God for themselves, and had done all they could to understand it." Ellet J. Waggoner
"Conviction is showing a man that he is guilty. Condemnation is the putting of the sentence upon him. We are already under condemnation, because of transgression. "Now the Lord comes to us and convicts us by his Spirit, but when He has brought us to this place where we are convicted and acknowledge the fact that we have sinned and are worthy of death, just there the Lord comes in and takes away the condemnation. He carries us to that point, and then the sentence is remitted." Ellet J. Waggoner
"Let the mind grasp the thought that the same Spirit that convinces of sin also convinces of righteousness. It is always a Comforter." ~Ellet J. Waggoner
