Walk in unity; “And do not grieve the Holy Spirit of God.”

I, therefore, the prisoner of the Lord, beseech you to walk worthy of the calling with which you were called, with all lowliness and gentleness, with longsuffering, bearing with one another in love, endeavoring to keep the unity of the Spirit in the bond of peace. There is one body and one Spirit, just as you were called in one hope of your calling; one Lord, one faith, one baptism; one God and Father of all, who is above all, and through all, and in you all. Therefore, putting away lying, “ Let  each one  of you  speak truth with his neighbor,” for we are members of one another. “Be angry, and do not sin”: do not let the sun go down on your wrath, nor give place to the devil. Let him who stole steal no longer, but rather let him labor, working with his hands what is good, that he may have something to give him who has need. Let no corrupt word proceed out of your mouth, but what is good for necessary edification, that it may impart grace to the hearers. And do not grieve the Holy Spirit of God, by whom you were sealed for the day of redemption. Let all bitterness, wrath, anger, clamor, and evil speaking be put away from you, with all malice. And be kind to one another, tenderhearted, forgiving one another, even as God in Christ forgave you.
Ephesians 4:1-6,25-32 - NKJV
