12 Therefore, my beloved, as you have always obeyed, not as in my presence only, but now much more in my absence, work out your own salvation with fear and trembling; 13 for it is God who works in you both to will and to do for His good pleasure. (Philippians 2:12–13, NKJV)
More than a few times we have heard this passage misused to endorse accepting people in error and the immorality it produces. Such brethren defy the existence of absolute truth while tacitly accepting the moral relativism it produces. Since good and sincere brethren disagree on certain doctrinal issues (which they define as gray areas), they conclude each one will have to just “work out their own salvation” on the matter. This view is applied to divorce and remarriage. One of the problems with using Philippians 2:12 this way is it results in accepting adulterers as if they are faithful Christians. No longer is the sinner rebuked and called to repentance. Now he or she is tolerated and allowed to “work out their own salvation.” People “commit adultery” when they divorce and remarry in violation of Matthew 19:9. How do you “work out your own salvation” as an adulterer? God only forgives the adulterer when the sinner repents, prays and ending the adulterous remarriage. “Work out your own salvation” means to keep on obeying God (read verse 12 again). You bring your salvation to its full accomplishment by obeying God, not by remaining in disobedience.
