It is interesting to follow the theme God uses, beginning at Genesis and ending at Revelation, that ultimately demonstrates how He can use dead wood to bring about new life. He even has Aaron's Rod, a dead piece of wood, bud and bear almonds in Exodus as a shadow of the resurrection Life He would produce from the dead wood we know as the Cross. Praise God for dead wood!

Acts 5:30 The God of our fathers raised up Jesus, whom ye slew and hanged on a tree.

Genesis 2:9 And out of the ground made the LORD God to grow every tree that is pleasant to the sight, and good for food; the tree of life also in the midst of the garden, and the tree of knowledge of good and evil.

Genesis 3:22 And the LORD God said, Behold, the man is become as one of us, to know good and evil: and now, lest he put forth his hand, and take also of the tree of life, and eat, and live for ever: Genesis 3:23 Therefore the LORD God sent him forth from the garden of Eden, to till the ground from whence he was taken. Genesis 3:24 So he drove out the man; and he placed at the east of the garden of Eden Cherubims, and a flaming sword which turned every way, to keep the way of the tree of life.

Revelation 2:7 He that hath an ear, let him hear what the Spirit saith unto the churches; To him that overcometh will I give to eat of the tree of life, which is in the midst of the paradise of God.
