“Brethren, if a man be overtaken in a fault, ye which are spiritual, restore such an one in the spirit of meekness; considering thyself, lest thou also be tempted.” Galations 6:1 (KJV)
How many times have you without any fault of your own found yourself dealing with a sin? You found yourself, deceived, believing wrongly, doing wrongly. You were “overtaken in a fault”. You have grieved over it. Then a “Spiritual” brother/sister who is bearing all those fruit of the Spirit comes and ministers to your need. By the love, compassion, and meekness you are restored to fellowship with God and the Body of Christ.
That is what it means to be a “Spiritual” Christian. The spiritual Christian does not condemn the fallen brethren, but seeks to restore the one who is grieving in their sin.
The next time you see a brother/sister in Christ overtaken in a fault seek his/her restoration. You could find yourself in that situation sometime later.
