Have you ever heard of friendship evangelism? You know, act as if you like someone until they become a Christian and believe just like you do. Well, there is a better way. Just love them as God does. How is that? Perfectly. What does that look like? You must love everyone totally and equally, "in order that you may be sons of your Father who is in heaven; for He causes His sun to rise on the evil and the good, and sends rain on the righteous and the unrighteous." and this is how "...you are to be perfect, as your heavenly Father is perfect." (Matthew 5:45, 48, NAS77)
I shared that idea with a friend some years back and he retorted, "I do. I hate everyone equally." Well, I guess that is a start but there is a way to be a much better friend to your-self. Your 'self' is the Spirit of love within trying to get out. Just step back and let Him out. Watch the Perfect One do His perfect thing through you and you will see that same one loving you back through those who hated you.
