Make them holy by your truth; teach them your word, which is truth.
A follower of Christ becomes pure and holy through believing and obeying the Word of God (Hebrews 4:12). He or she has already accepted forgiveness through Christ's sacrificial death (Hebrews 7: 26,27). But daily application of God's Word has a purifying effect on our minds and hearts. Scripture points out sin, motivates us to confess, renews our relationship with Christ, and guides us back to the right path.
