Genesis sets the foundation for understanding the rest of the storyline of the Bible, in particular the first few chapters.   The Tree of Life and the Tree of the Knowledge of Good and Evil play a significant role throughout that storyline of the Scriptures, but we may not always recognize it when we see it.
Scriptures that I read or reference include… Genesis 2:7-9, 15-17; John 17:3; Genesis 3:22-24; Exodus 3:2; Deuteronomy 21:22-23; Psalm 1:1-3; Jeremiah 17:7-8; 1 Peter 2:24; Isaiah 53; Galatians 3:13; Revelation 2:7; Ezekiel 47:1-12; Revelation 22:14.
There are other Scriptures that develop these ideas, can you find others?
