Jesus describes love for those who are hostile towards me as the hallmark of the heavenly Father (Matthew 5:43-48). We should allow ourselves to be motivated by this love of God.

Someone is an enemy to me, not because I have something against them, but because they are against me for some reason.

Treat all people equally and give even those who are hostile to you a chance to repent.

The heavenly Father, who lets the sun shine on all people and also gives everyone the rain, is a role model.

God wants to reconcile all people with Himself. That is why no hatred should emanate from people who live with God. We wish all people peace with God. And that is why we treat all people equally.

Loving our enemies means treating them with respect and not closing the door to reconciliation. David exemplified this very impressively in his relationship with Saul.
