There is a tremendous sense of freedom in living a blameless life. Job was blameless. Neither Satan nor any person could accuse him of wrongdoing. Even through the most rigorous tests, Job remained above reproach.
The apostle Paul said he diligently sought to relate to others in such a way that he would never regret his actions (Acts 24:16). This desire should be ours as well. The Book of Revelation indicates that those in heaven will be blameless (Rev. 14:5). This condition does not mean they never sinned on earth, but that God forgave their sins and granted them His righteousness.
Blameless does not mean perfect. It means that in every situation you do the correct thing. If you sin against someone, you confess your sin and ask for forgiveness. If you sin against God, you repent and begin to obey Him (Prov. 28:13). Often the way you handle your sin is as important as the sin itself. When you become aware of your transgression, seek to be blameless in the way you deal with it. If you attempt to conceal your sin, deny it, justify it, or blame others for it, you make the original offense much worse.
Have you been blameless in your dealings with God and others? When you have failed to treat people as you should, have you responded with integrity as you reconciled with them? If you are to be blameless, you must do everything in your power to correct any wrongdoing and reconcile any broken relationship. There is a profound sense of peace for the one whose way is blameless!
