The oil of gladness that keeps the engine of fellowship running smoothly is forgiveness. The forgiveness of God in Christ is what motivates the forgiveness we extent to one another, as well as all the kindness and compassion.
Scripture is abundantly clear that those who call themselves Christians who will not forgive those who have wronged them, cannot be forgiven by God (e.g. Mt. 23ff). We pray this regularly: “forgive us our trespasses, as we forgive those who trespass against us.” This is not a “works righteousness,” as though we are trying to earn God’s forgiveness. It is rather the natural overflow of receiving God’s complete forgiveness.
The Text: “… Let all bitterness, and wrath, and anger, and clamor, and evil speaking, be put away from you, with all malice: And be ye kind one to another, tenderhearted, forgiving one another, even as God for Christ’s sake hath forgiven you” (Eph. 4:29-32).
