 We have the practical effects of the gospel. We have thousands and thousands of testimonies of people whose lives have been changed. We don't have unbelief because of the lack of evidence. But according to Hebrews, listen to this. Beware, brethren, that there be in any of you an evil heart of unbelief. We have unbelief because of the evil in our hearts. We don't believe because we don't want to believe.
