To have no fear of death is to truly live the Christian life. Living for something worth dying for, which is faith in Jesus Christ. True liberation comes by accepting death with the hope to see Christ at His second coming, when resurrected.
Jesus said, “whoever wants to save his life will lose it, and whoever loses his life for my sake will find it.” Matthew 16:25
The fear of death is the heart of the issue. And the cause of ignorance. Not allowing us to freely live by faith. Being fearful of the possible ramifications. Faultering to not make choices in faith that can be a detriment to our souls. Fearing those who can imprison, torture and kill the body.
For this reason, many are unfaithful. Trying to save their life. Many are attempting to establish their own heaven on earth. To make it be the most comfortable, and experience the most pleasure that they possibly can, before they die.
