Job 27:4, “My lips shall not speak wickedness, not my tongue utter deceit.”
Even with all that Job was going through, he determined that he was not going to speak wickedness. Everything he had had been taken from him. Along with that, his wife and friends turned their backs on Job, yet Job still would not speak wickedly.
If Job can go through all of that and still determine not to speak wickedly, we have no excuse to speak wickedly against God or against others. I Corinthians 15:33 says, “Be not deceived: evil communications corrupt good manners.” We ought not to allow our evil and wicked word corrupt us, but our desire should be that of Psalm 19:14 which says, “Let the words of my mouth, and the meditation of my heart, be acceptable in thy sight, O Lord, my strength, and my redeemer.” I pray that what comes out of our mouth would be acceptable in the sight of the Lord.
