“I rejoiced greatly that I found of thy children walking in truth, as we have received a commandment from the Father.” (2 John 1:4)
This beautiful metaphor, “walking in truth,” is found only in the two one-chapter epistles of John—here in our text, and in 3 John 1:3 and 4. This principle should indeed characterize our daily lives, since our Lord and Savior is Himself “the truth” (John 14:6), the Word of God that we believe is “truth” (John 17:17), and the Holy Spirit who indwells our bodies is the very “Spirit of truth” (John 15:26).
The New Testament also uses other characteristics of the Christian life under this figure of walking. When a person is born again through faith in Christ and testifies of this by following the Lord in baptism, he or she is said to be raised to “walk in newness of life” (Romans 6:4).
Then, since the Holy Spirit has come to indwell our bodies, to comfort, guide, and constrain us as needed, we are exhorted to “walk in the Spirit, and ye shall not fulfill the lust of the flesh” (Galatians 5:16). Furthermore, we are commanded to “walk in love, as Christ also hath loved us” (Ephesians 5:2). This is not erotic love, of course, or even brotherly love, but unselfish agape love that sacrifices its own interests for the needs of others.
There are still more such exhortations. “Walk in wisdom toward them that are without, redeeming the time” (Colossians 4:5). Furthermore, we are to “walk in the light, as he is in the light” (1 John 1:7).
All of these and other similar admonitions can be summarized as simply following the example of Christ. “He that saith he abideth in him ought himself also so to walk, even as he walked” (1 John 2:6). “He that followeth me,” said Jesus our Lord, “shall not walk in darkness, but shall have the light of life” (John 8:12).
