The Central Idea of the Text is that Jesus’ signs and teaching hardened those who were negative (John 12:37-41, 47-48) and softened those who were positive (John 12:42-46). Jesus had performed many signs as a witness that He is Messiah; however, no amount of evidence would suffice for those who were negative to Him and His message (John 12:37).  Isaiah too had experienced negative volition concerning the message God gave him for Israel (Isa. 6:8-13; 53:1; John 12:38-41).  Though most did not believe in Jesus as Messiah, there were some who did, even among the rulers, though they loved the approval of men more than God (John 12:42-43).  Jesus’ final public words revealed that to believe in Him was the same as believing in the Father who sent Him (John 12:44-45).  Jesus came as the Light into a world of darkness and those who believe in Him are transferred to His kingdom (John 12:46; cf. Col. 1:13-14).  Those who reject Jesus’ words will, eventually, be judged by those words (John 12:47-50).
