What is truth? Pilate asked Jesus this question in the judgment hall (John 18:38) before returning outside to tell the Jews that he found no fault in him.
Although Jesus didn’t answer Pilate, we know from his own words that He is the truth (John 14:6). He is also the Word (John 1:1, John 1:14; Revelation 19:13). When Jesus prays to the Father just before he’s taken in the garden of Gethsemane He says, “Sanctify them through thy truth: thy word is truth.” (John 17:17), which is a beautiful confirmation of Him being God manifest in the flesh (1 Timothy 3:16; John 1:14; 1 John 1:1-2).
Jesus tells us in his own words that the truth will make us free. Since He is the truth, He is the one making us free.
Then said Jesus to those Jews which believed on him, If ye continue in my word, then are ye my disciples indeed; And ye shall know the truth, and the truth shall make you free. (John 8:31-32)
And when Jesus makes us free, we are free indeed (John 8:36), the fulfilment of the prophecy in Isaiah that He will proclaim liberty to the captives:
The Spirit of the Lord GOD is upon me; because the LORD hath anointed me to preach good tidings unto the meek; he hath sent me to bind up the brokenhearted, to proclaim liberty to the captives, and the opening of the prison to them that are bound; To proclaim the acceptable year of the LORD, and the day of vengeance of our God; to comfort all that mourn; (Isaiah 61:2)
Jesus himself confirmed that he was the fulfilment of this prophecy when he read from the Book of Isaiah in the synagogue at Nazareth:
The Spirit of the Lord is upon me, because he hath anointed me to preach the gospel to the poor; he hath sent me to heal the brokenhearted, to preach deliverance to the captives, and recovering of sight to the blind, to set at liberty them that are bruised, To preach the acceptable year of the Lord. And he closed the book, and he gave it again to the minister, and sat down. And the eyes of all them that were in the synagogue were fastened on him. And he began to say unto them, This day is this scripture fulfilled in your ears. (Luke 4:18-21)
What a glorious God we serve!
