Matthew 5:9 (ESV)
Blessed are the peacemakers,
for they shall be called sons of God.
The only begotten Son of God, Peace.
There are things you can pray, do and say that will beget (cause, produce) peace. Be slow to judge, quick to encourage. Be the first to say, “I’m sorry.” Drop the grudge. Be kind and merciful to others. Pray that they will have Peace. And thus you will be called sons of God.
