How do we know that the tree of life represents Christ?

The tree of life, placed in the midst of the Garden of Eden, is a powerful image representing Jesus Christ. In Proverbs 3:18, wisdom is personified as a tree of life, illustrating that true wisdom and life are found in Christ. As we trace the theme of life throughout Scriptures, including Revelation 2:7, we see that access to the tree of life is given to those who overcome through faith in Christ. Thus, the tree signifies not only physical sustenance but ultimately points to Christ as our spiritual sustenance and eternal life.
