What does it mean to be spiritually immune from harm?

Being spiritually immune from harm means that those who are genuinely in Christ and have been sealed by the Holy Spirit are secured from spiritual death and eternal condemnation. This immunity is guaranteed by God's promise of preservation, as seen in Revelation 7:3, which describes the sealing of God’s servants. Such believers may experience tribulations and trials in this world, but they are assured that their eternal destiny is secure in Christ. Romans 8:38-39 emphasizes that nothing can separate them from the love of God, highlighting the deep assurance found in their relationship with Him. As they focus on Christ and the hope of eternal life, believers are empowered to endure persecution without fear of ultimate harm.
