Do not lie to one another, since you have put off the old man with his deeds, and have put on the new man who is renewed in knowledge according to the image of Him who created him, where there is neither Greek nor Jew, circumcised nor uncircumcised, barbarian, Scythian, slave nor free, but Christ is all and in all.
God is called the “God of truth” (Isaiah 65:16). The Holy Spirit is the “Spirit of truth” (John 16:13). Christ said, “I am … the truth” (John 14:6). No one can have fellowship with the holy trinity who does not walk in the truth (2 John 4; 3 John 4). God desires truth in the inward parts (Psalm 51:6). Falsehood of every kind is hateful to Him. There is nothing that so manifests the alienation of the natural man from God as his tendency to falsehood. Of the wicked we are told that they go astray from their very birth speaking lies (Psalm 58:3). Satan himself is the father of lies (John 8:44). It is he who injects the venom of untruthfulness into the heart of man (Acts 5:3). Only by the new birth can this lying spirit be overcome. It is as the regenerated man yields himself to God as one alive from the dead that he learns to delight in the truth objectively revealed, and to walk in the truth subjectively.
O Jesus Christ, grow Thou in me,
And all things else recede;
My heart be daily nearer Thee;
From sin be daily freed.
In Thy bright beams which on me fall,
Fade every evil thought;
That I am nothing, Thou art all,
I would be daily taught.
