Hebrews 12:14,15 (NLT) 14 Work at living in peace with everyone, and work at living a holy life, for those who are not holy will not see the Lord. 15 Look after each other so that none of you fails to receive the grace of God. Watch out that no poisonous root of bitterness grows up to trouble you, corrupting many.
As Paul tells us in Romans 12, we should do everything that we can do to live in peace with our fellow man. Add to that, the fact that we should strive to live a Holy life. God tells us to be Holy because He is Holy. Once we are indwelt by God’s Holy Spirit, it should be our inclination to follow the example of Jesus in all that we do. That requires us to not only seek peace and holiness, but to teach others so that no one fails to receive the gospel of Jesus Christ. To do this, we must avoid gossip and rumor mongering. If we practice those things, we hurt others instead of helping. Do this with humility and love so that no one can blame you. When you are wrongfully blamed, quickly forgive the person. Don’t hold grudges and allow a “root of bitterness” to grow in your heart. This will, first of all, destroy you and then those around you.
