John 3:19-20

John 3:19-20. That light is come into the world, and men loved darkness rather than light, because their deeds were evil. For every one that doeth evil hateth the light, neither cometh to the light, lest his deeds should be reproved.

This is the secret of infidelity. This is the reason of all opposition to Christ. It is love of sin. Trace it home to its den and lair, and you shall find that it is love of sin that breeds hatred of Christ. Men do not see because they do not want to see. They do not want to see too much lest they should be uneasy in their present state of life. So they kick against Christ, and try to put out the light of his gospel, least they be reproved by it.
