Why do you expect to change a evil world without the love of Christ? Do you really believe forcing people to act like Christian’s instead of proclaiming the gospel and allowing them to make up their own minds in there own time, is what we should do as Christian’s?
Hating sin and declaring that the wrath of God is coming on the Earth for these sins is love for the sinners. When people are in hell for eternity they will blame those who refused to tell them the truth.
I heard the testimony of a gang member who died and went to hell. He was resuscitated and said he couldn't believe Christians knew about hell and didn't tell anyone, to him that was the real hate.
This is the gospel:
24 Therefore whosoever heareth these sayings of mine, and doeth them, I will liken him unto a wise man, which built his house upon a rock:
25 And the rain descended, and the floods came, and the winds blew, and beat upon that house; and it fell not: for it was founded upon a rock.
26 And every one that heareth these sayings of mine, and doeth them not, shall be likened unto a foolish man, which built his house upon the sand:
27 And the rain descended, and the floods came, and the winds blew, and beat upon that house; and it fell: and great was the fall of it.
