What does it mean that our sickness is not unto death?

When Jesus declared that Lazarus's sickness was not unto death, He emphasized that for those in Christ, physical death does not lead to eternal separation from Him. Instead, it is part of the journey towards glorification. As believers, we have assurance that physical trials, including sickness, are temporary and serve a greater purpose in God's plan for our lives. Romans 8:38-39 reassures us that nothing—including death or life—can separate us from God's love. Hence, our final destiny in Him is not determined by earthly sufferings.
