Jesus said to him, “I am the way, and the truth, and the life. No one comes to the Father except through me. ~John 14:6
How do we know what is True?
Paul tells the church at Corinth, “Every charge must be established by the evidence of two or three witnesses.”
In other words, if a charge against someone is to be true and have weight, two or three witnesses must be present. But where is Paul getting this idea?
Deuteronomy 17:6; Deuteronomy 19:15-21; Proverbs 18:17; Matthew 18:15-20
There are three uses of the law:
- Restrain sin
- Shows people their sin and points to mercy/grace outside themselves
- For those in Christ it is normative
Christ is central as the one who has saved his people from the law’s demands and the one who has earned for them the gift of Spirit-wrought obedience1
I bring the three uses of the law up to simply point out, the law is the expression of God’s character. It is because of Who God is in Himself that the law is true and right.
Hold on to this thought for a moment.
What does it mean that Jesus is Truth?
Who is Jesus? Jesus is the Second Person of the Trinity. Who is the Trinity? The Father, Son, and Holy Spirit.
Jesus is Truth because both the Father and Holy Spirit are witnesses to this fact. Likewise, the Son and the Holy Spirit are witnesses to the Father, and the Father and the Son are witnesses to the Holy Spirit (see John 5:37; John 8:18; John 15:26).
The Trinitarian God bears witness of Himself because of Who He is in Himself
I can do nothing on my own. As I hear, I judge, and my judgment is just, because I seek not my own will but the will of him who sent me. If I alone bear witness about myself, my testimony is not true. There is another who bears witness about me, and I know that the testimony that he bears about me is true. You sent to John, and he has borne witness to the truth. Not that the testimony that I receive is from man, but I say these things so that you may be saved. He was a burning and shining lamp, and you were willing to rejoice for a while in his light. But the testimony that I have is greater than that of John. For the works that the Father has given me to accomplish, the very works that I am doing, bear witness about me that the Father has sent me. And the Father who sent me has himself borne witness about me. His voice you have never heard, his form you have never seen, and you do not have his word abiding in you, for you do not believe the one whom he has sent. ~John 5:30-38
Jesus is Truth because God testifies to it.
