You will know the truth
What does it mean that you will know the truth in John 8:32?
Jesus stated plainly that the mark of a true disciple of Christ is that he remains faithful to His teachings. He told the Jews who believed in Him, “If you abide in my word, you are truly my disciples, and you will know the truth, and the truth will set you free” (John 8:31–32, ESV).
The word know in John 8:32 is translated from a Greek verb that means “to know experientially.” Understanding something with the mind or intellect, often called “head knowledge,” is different than knowing something experientially. We can know that something is bad for us yet still do it. But when we take Jesus at His word and practice “the truth that comes from him,” then we will “throw off [our] old sinful nature and [our] former way of life” and “let the Spirit renew [our] thoughts and attitudes” so that the truth we live by sets us free “to be like God—truly righteous and holy” (Ephesians 4:20–24).
We shall know the truth in a way that sets us free from our old sinful way of life when we know Jesus experientially, in word, deed, and truth (see Colossians 3:17; 1 John 3:18). “Our actions will show that we belong to the truth” (1 John 3:19, NLT).
Knowing the truth means experiencing Jesus Christ by accepting His teachings as absolute truth and then living in faithful obedience to them. We receive the message of the gospel and the teachings of Christ, and then we abide by them. The apostle John often framed the concept of true discipleship as knowing the truth of Christ experientially: “And we can be sure that we know him if we obey his commandments” (1 John 2:3, NLT; see also 1 John 2:29; 3:16, 24).
Knowing the truth is a rock-steady way of life. John 8:32 upholds the biblical concept that truth is the only dependable foundation for constructing one’s life (see also Psalm 26:3). Jesus taught, “Anyone who listens to my teaching and follows it is wise, like a person who builds a house on solid rock. Though the rain comes in torrents and the floodwaters rise and the winds beat against that house, it won’t collapse because it is built on bedrock. But anyone who hears my teaching and doesn’t obey it is foolish, like a person who builds a house on sand. When the rains and floods come and the winds beat against that house, it will collapse with a mighty crash” (Matthew 7:24–27, NLT). If we plant our feet firmly on Christ’s truth and follow the path of His teachings, nothing can shake, derail, or destroy us.
Jesus is the personification of truth (John 14:6). Only He embodies the truth that sets us free (Galatians 5:1; Romans 6:18; John 8:36). Those who know the truth are born-again believers who live in fellowship with God through a relationship with Jesus Christ: “And we know that the Son of God has come, and he has given us understanding so that we can know the true God. And now we live in fellowship with the true God because we live in fellowship with his Son, Jesus Christ. He is the only true God, and he is eternal life” (1 John 5:20, NLT).
You will know the truth also expresses the moral commitment of genuine disciples to do the will of God (John 7:17; 14:21, 23; James 1:25). We know the truth in the person of Jesus Christ, who prayed to the Father for us to be “made holy” by His truth and gave His own life as the sacrifice that made it possible for us to live out that truth (see John 17:14–19). Moreover, Jesus asked the Father to send us “the Holy Spirit, who leads into all truth” (John 14:16–17, NLT; see also Ephesians 1:13).
When Jesus said, “You will know the truth, and the truth shall make you free,” He was telling His followers that obedience to God is the only way to experience true liberation—spiritual freedom from sin. The freedom Jesus offers is restored fellowship with the Father, who is the source of all true life. And the mark of one who has received this life is to remain faithful to His teachings.
