Only the love of the HolySpirit can enable you to LoveYourEnemy in the right way.
It is important to note that Jesus loved His enemies enough to die for them.
But He also -> rebuked them Mat 23:29, -> called them names Mat 3:7, -> warned them of perishing except they repent Luk 13:3 and -> ultimately rejected them that rejected Him Mat 12:41,42 Rom 11:25.
We need to discern the difference between a lost person who is our enemy and a reprobate person who is our enemy. A lost person should hear the mercy of Christ from us. The reprobate person should hear the judgment of Christ from us.
