(Red-letter portions New Testament)
Matthew 5:23, 24, "So if you are standing before the altar in the Temple, offering a sacrifice to God, and you suddenly remember that someone has something against you, leave your sacrifice there beside the altar. Go and be reconciled to that person. Then come and offer your sacrifice to God."
Jesus desires reconciliation not separation, from each other or from Him.Jesus did not say "stay away from church, don't take communion, and don't give to the offering if you are fussing with someone." He said, "Be reconciled."How can Jesus help you stop fussing, if you cut yourself off from Him? How is not going to church going to help you bury the hatchet?
Jesus is addressing the self-righteous piety that some religious folks have when they harm others and then go off to church like nothing happened. A mob boss that has people killed is not justified in God's eyes because he attended church or gave some of his drug money to pay for the new church organ. God wants reconciliation more than He wants a new church organ.
Work towards reconciliation. The best way to accomplish that is to go to church, humble yourself, accept the forgiveness Jesus offers, give your life to Him, have communion with Him, and receive the spiritual strength needed to go to your brother and seek reconciliation.
It may take awhile, so begin the process of reconciliation, today. Come to Jesus, today. Begin a relationship with Him, today. Go to church, get right with God, as soon as possible, and it will help you to be reconciled with your brother.
