Is Matthew 5.44 part of God’s moral law?

“But I say to you, love your enemies and pray for those who persecute you” Mt. 5.44.

Does God require His children to do something He does not do?
Is it disobedient *not* to love/pray for our enemies?
Is it Christlike to obey this command and to love/pray for our enemies?
Is Matthew 5.44 part of God’s moral law?
If so, can God act contrary to His moral law since it is an expression of His character?
If so, would God be loving His enemies if He refused to save them when He could do so?
(Common grace does not address this question).
So, how can the doctrine of unconditional election be true when it requires God to deny His own character?”
