Matthew 5:9, 16, 23-24, 44-45

“Blessed [spiritually calm with life-joy in God’s favor] are the makers and maintainers of peace, for they will [express His character and] be called the sons of God. [Heb 12:14]

Let your light shine before men in such a way that they may see your good deeds and moral excellence, and [recognize and honor and] glorify your Father who is in heaven.

So if you are presenting your offering at the altar, and while there you remember that your brother has something [such as a grievance or legitimate complaint] against you, leave your offering there at the altar and go. First make peace with your brother, and then come and present your offering.

But I say to you, love [that is, unselfishly seek the best or higher good for] your enemies and pray for those who persecute you, [Prov 25:21, 22] so that you may [show yourselves to] be the children of your Father who is in heaven; for He makes His sun rise on those who are evil and on those who are good, and makes the rain fall on the righteous [those who are morally upright] and the unrighteous [the unrepentant, those who oppose Him].
