[...] I am seldom surprised when the gospel message stirs up ire in them who hear it.

Of course, ire is not the only response for those who hear the gospel. Ire is however the common response for God's enemies. But some hear the gospel and reject it outright. Some hear It and though they know it is the truth, they just cannot let go of the worldly things they love so much. Others hear It and know it's true, but fear the reactions of their friends and family. Some hear and accept It gladly, but just cannot commit. Others just keep putting it off until it's too late.

Remember, belief outside of salvation is possible, I would go so far as to say that all men actually know the truth, no matter what they say. Romans 1:20 (KJV)
20 For the invisible things of him from the creation of the world are clearly seen, being understood by the things that are made, even his eternal power and Godhead; so that they are without excuse:

And you can bet Satan and his legions believe; James 2:19 (KJV)
19 Thou believest that there is one God; thou doest well: the devils also believe, and tremble.

Nobody will get to stand before the Almighty and say he didn't know he had to bow before Him to live. The God of this universe is not lacking in any regard. But as I said in the post above, the charter of the true Church is to point men to Christ. And the fortunate ones who hear the good news, (thusly having their consciences confirmed by the message of Christ as delivered to them by the Church) and believe on Him shall... "have everlasting life." And are at that time sealed into the body of Christ by the Holy Spirit.

When the Church calls out sin for what it is, that certainly does not mean we are in any way guilty of judging others. God hates sin, but loves the sinner. But they have to come to Him asking for forgiveness.
