When you are praying, and you remember that you are angry with another person about something, then forgive that person. Forgive them so that your Father in heaven will also forgive your sins.”
“Don’t judge other people, and you will not be judged. Don’t condemn (find guilty) other people, and you will not be condemned. Forgive other people, and you will be forgiven.
Don’t be angry with each other, but forgive each other. If another person does something wrong against you, then forgive that person. Forgive other people because the Lord forgave you.
Yes, you must show mercy to other people. If you do not show mercy, then God will not show mercy to you when he judges you. But the person who shows mercy can stand without fear when he is judged.
So we can see who God’s children are. Also, we can know who the children of the devil are. The people who don’t do what is right are not children of God. And the person who does not love his brothers and sisters \{in Christ\} is not a child of God.
