Therefore, putting away lying, “Let each one of you speak truth with his neighbor,” for we are members of one another. (Ephesians 4:25, NKJV)
In this familiar Bible verse, a reason to be honest with one another is given in it, with another reason given just prior to it. “Therefore” draws our attention to what was just said, namely, that we have “put on the new man which is created according to God, in true righteousness and holiness” (Eph. 4:24). When we heard the gospel and “learned Christ,” we were taught to put off the old person of corruption and “deceitful lusts,” and to be “renewed” in the spirit of our mind (Eph. 4:20-23). We choose to be honest and to stop being deceitful. Honesty is a choice of faith. Secondly, we tell the truth because we are members of each other in the body of Christ (v. 25). The hand does not lie to the arm; the ear does not lie to the eye. Neither are Christians to lie to one another. As members of the body of Christ (His church), we are connected to each other – “members of one another” (Rom. 12:5). Christ (our head) knows when we do not speak the truth, so we ought not to try to deceive one another. Honesty is a choice we make because we think of others as better and more important than ourselves. Finally, be sure you do not lie to yourself. Deceiving yourself that lying is acceptable hardens your heart against truth and leads to eternal death (Rev. 21:8).
