When we see how merciful God has been to us, we will be in the right frame of mind to extend grace and mercy to others who need it.
By loving, we can be complete (perfect) disciples.
We should not be concerned with our "rep." If we are concerned with what others think of us, it is probably our pride that could be hurt. This should not be a concern for a Christian.
Jesus closes this lesson with a warning that, if we do not resolve the sin of anger in ourselves, we will have to deal with the consequences. God will not intervene to "fix" the mess we have made when our own anger is the cause.
Our own righteousness is no better than that of the Scribes and Pharisees. We need something much greater to justify us before a Holy God.
We do not have to slavishly seek to please God by our will or works. We can, with great liberty, live our live in thankful righteousness.
Our spirit is crying out in thankfulness for the mercy of God. Let us not quench that cry!
All of the descriptions of the elect child of God given by Jesus are evidences of the Spirit of God already dwelling inside the person.
The gospel is not a warning that judgment is coming. It is a declaration that the judgment has been made and the elect are justified in Christ.
The world and the devil may label you by your sin but your Heavenly Father does not. He sees you through the blood of Christ. God sees you as righteous.
