Walking in truth is the essential message of this short epistle. As in his first epistle, the Apostle John connects truth and love as key, inseparable elements of the sanctified life. He said Jesus came full of truth and love. And He prayed to the Father to sanctify His disciples by the truth, which is found in God’s word. Real love can only be experienced in light of God’s truth, and God’s truth can only be lived out in love, love for God and for one another.
