Even those who want to go to heaven would rather kill than be killed.
People debate over whether or not there is a literal Hell, in the literal sense often described as fire and eternal torture, which, to many, seems to be too harsh a punishment. If men really want to fear something, they should be fearing separation from God, the supposedly more comforting alternative to a literal Hell. For separation from the authorship of love, mercy, and goodness is the ultimate torture. If you think a literal Hell sounds too bad, you are very much underestimating the pain of being absolutely, wholly separated from the goodness while exposed to the reality of the holiness of God.
Therefore, when a person refuses to come to Christ it is never just because of a lack of evidence or because of intellectual difficulties: at root, he refuses to come because he willingly ignores and rejects the drawing of God's Spirit on his heart. No one in the final analysis fails to become a Christian because of a lack of arguments; he fails to become a Christian because he loves darkness rather than light and wants nothing to do with god.
