I dont believe that someone can love someone to Jesus. I do believe that sharing His word is important. When Jesus began His ministry, He told people to repent, He wasnt just a really nice guy to everyone.
Before someone turns that into something its not, Im not saying go out and force your will on everyone. But lets say you do start ministering to someone who has not come to Him, and they are caught up in sin. You absolutely have to tell them they need to repent.
There is such a thing as going to far, sure. But the rise in people who call themselves Christian but have a fear of speaking the truth of the word of God, or have taken up the teaching that its mean to say sin is wrong, is alarming to me. Its not hateful to bring people to the word of God. The message isnt "Im better than you", its that even though we have all died to sin, He gave His life as a ransom for ours, and that through Him we can be saved. If you know the warning, but do not give it to your brother, his blood is on your hands.
