I have many things to say and to judge concerning you, but He who sent Me is true; and I speak to the world those things which I heard from Him. (John 8:26, NKJV)
The words of Jesus are the very words of God the Father, who sent Him to the world. His words contain God’s judgments of us. We must be willing and ready to hear and accept God’s judgments, since they are “true and righteous altogether” (Psa. 19:9). When the word of Christ exposes our sins and convicts us as sinners it is God calling us to repentance and salvation. His word is always true, therefore, it is indeed foolish to ignore, to refuse and to reject it: “He who rejects Me and does not receive My words, has that which judges him–the word that I have spoken will judge him in the last day” (Jno. 12:48). Better to receive God’s judgments now, while there is time to repent, than on the day of judgment when that time will have passed forevermore.
