John 8:46

Convinceth. Gr. elegcho, “to convict,” “to reprove,” here, the former. The word is translated “convict” in v. 9, and would suitably be so translated in ch. 16:8, where the KJV renders it “reprove” (see comments there). Jesus appeals to the knowledge of the Jews concerning His sinless life. He Himself had given testimony of His entire conformity to the Father’s will (ch. 8:29). Despite all the spying of the religious leaders, not one stain of sin had been detected. Their silence upon this occasion confirmed His testimony. Since they tacitly admitted the purity of Jesus’ life, the irrationality of their course lay effectively exposed.

On the absolute sinlessness of Jesus see 2 Cor. 5:21; Heb. 4:15; 7:26; 1 Peter 1:19; 2:22; 1 John 3:5.
