Reconciliation

If we do not love another follower of Jesus, God’s love in not in us.
Those who say, "I love God," and hate their brothers or sisters, are liars; for those who do not love a brother or sister whom they have seen, cannot love God whom they have not seen. I John 4:20

If we do evil against another follower of Jesus, we are children of the devil.
The children of God and the children of the devil are revealed in this way: all who do not do what is right are not from God, nor are those who do not love their brothers and sisters. I John 3:10

Anyone who does evil against others will not enter the kingdom of God.
Now the works of the flesh are obvious: fornication… enmities, strife, jealousy, anger, quarrels, dissensions, factions, envy, drunkenness, carousing, and things like these. I am warning you, as I warned you before: those who do such things will not inherit the kingdom of God. Galatians 5:19-20

If we have caused a problem between us and another follower of Jesus, it is not right between us and God.
So when you are offering your gift at the altar, if you remember that your brother or sister has something against you, leave your gift there before the altar and go; first be reconciled to your brother or sister, and then come and offer your gift. Matthew 5:23-24

If we have wronged another follower of Jesus, we must make it right
Come to terms quickly with your accuser while you are on the way to court with him, or your accuser may hand you over to the judge, and the judge to the guard, and you will be thrown into prison. Matthew 5:25

If we owe anyone anything, we should pay it off.
Pay to all what is due them… Owe no one anything, except to love one another. Romans 13:7,8

We need to forgive others of their debts and sins against us.
For if you forgive others their trespasses, your heavenly Father will also forgive you; but if you do not forgive others, neither will your Father forgive your trespasses. Matthew 6:14-15
