God is life. In Him, we live and move and have our being. Dust was just dust until God breathed life into it. The body returns to dust when God’s spirit leaves it. We are nothing without Him.
The tree of life represents God—always an option presented; never a decision forced.
God alone has immortality. We mortals may put on His immortality when He returns. That’s our choice to make.
“When this corruptible will have put on incorruption, and this mortal will have put on immortality, then the saying that is written shall come to pass: ‘Death is swallowed up in victory’” (1 Corinthians 15:54).
