Do you follow Matthew 5:44-48 and is it hard ?

That's right those Scripture that you there are citing are showing that Gods loves all mankind and wants to save all, even those who are against him, so we should follow his example and do the same, and love our enemies. Yes I do follow that advice in the Scriptures but that does not mean that I can do it perfectly, yes it is hard, for I am not perfect, only God and his Son Jesus Christ are perfect, but the main thing here is to try, and no I don't expect a medal, just to please God. That is my reward.
