Why is understanding physical death important for Christians?

In Genesis 3:22, God expels Adam from the Garden of Eden to prevent him from eating from the tree of life and living forever in his fallen state. This act demonstrates God's mercy; physical death becomes a necessary step for restoration and ultimate fellowship with Him. Thus, for Christians, understanding physical death is crucial as it serves as a transition to eternal life rather than an end. By viewing death through the lens of scripture, Christians can find hope and reassurance, knowing that physical death leads to spiritual renewal and eternal life with God.
