And early Christians converted because.... Sorry, but that was a senseless set of statements you just made.
What I said was entirely sensible. And I do think there is a certain lack of humility in those who think that they know that EVERY person who hears the gospel once or twice or even more often does not convert because they are stubborn or sinful or rejecting God altogether. Since when did they learn to read minds? The human mind, the human condition, the variation of cultures and up-bringing and experiences that strongly influence each individual should be taken into consideration. If I had been born Muslim I would probably stay Muslim. I just don't know if I would have converted or not. If I was raised all my life to believe that being a Muslim was the most pleasing thing to God, and I want to please God, then why would I switch to another faith?
Your faith is a gift, no boasting about it is allowed and one way to boast is to look down your nose at non-Christians and think you know that they are going to hell and you are not. There is every reason to be grateful and no reason to look down your nose at non-Christians or to denigrate those who live good lives or to denigrate their good works. I am humbled by the good works of some non-Christians.
Jesus told the Pharasees. 'If you were blind you would have no sin. But "We see, you say" and so your sin remains.' What this means to me is that some are really blinded from impediments that keep them from giving the gospel a fair hearing. In such cases they may not, MAY not be culpable for not converting. But if, like the Pharasees, you really do see it but continue in your ways, then your sin remains.
