“Thus,
You may be
Sons of your Father
Who is in heaven.
He makes his sun rise
On the evil ones
As well as the good ones.
He sends rain
On the righteous
As well as the unrighteous.”
ὅπως γένησθε υἱοὶ τοῦ Πατρὸς ὑμῶν τοῦ ἐν οὐρανοῖς, ὅτι τὸν ἥλιον αὐτοῦ ἀνατέλλει ἐπὶ πονηροὺς καὶ ἀγαθοὺς καὶ βρέχει ἐπὶ δικαίους καὶ ἀδίκους.
Matthew has a consequence for loving your enemies, much like Luke, chapter 6:35. They would become the children or sons of their heavenly father (ὅπως γένησθε υἱοὶ τοῦ Πατρὸς ὑμῶν τοῦ ἐν οὐρανοῖς). Their father in heaven makes the sun rise on both the bad and the good people (ὅτι τὸν ἥλιον αὐτοῦ ἀνατέλλει ἐπὶ πονηροὺς καὶ ἀγαθοὺς). He also sends rain to both the righteous and the unrighteous (καὶ βρέχει ἐπὶ δικαίους καὶ ἀδίκους). Clearly God is a powerful paternal person who takes care of both the just and the unjust people.
