Follow peace with all men, and holiness, without which no man shall see the Lord: Hebrews 12:14 KJV
Being contentious and mean spirited will make you sick, infirm, and, eventually, kill you. It will cut you off from God and leave you subject to the vain imaginations of your own mind and even under the influence of the “fiery darts” of demon spirits.
Being loving and kind hearted will heal you. Such is the way of God.
“Forgive and you shall be forgiven” is a command as is “love one another.”
There is no place for, nor excuse for, schism (strife and contention) as we walk in the loving kindness and forgiveness in Christ.
Choose life, peace, health. The choice is in your heart and expressed through your lips.
There is that speaketh like the piercings of a sword: but the tongue of the wise is health. Proverbs 12:18 KJV
Death and life are in the power of the tongue: and they that love it shall eat the fruit thereof. Proverbs 18:21 KJV
