The Tree of Life is the Fact that this is GOD'S LIFE; Thus, He is Lord of It

As former United States President Joseph Biden would say, "Think about it."  When there was nothing--no dimensions, no infinity, no "thing" in any way, shape or form, there was . . . well, we don't know.  There was (...?).  And (...?) had the power to create thing out of nothing.  The nothing that It Itself was.  Everything is from It.  Everything is OF It.  It has made us to live, and it gives us life; but we and the life He has "given" us nevertheless and for evermore are HIS.  He owns us.  STAY in that channel with Him as your lord, and everything is all right.

The Tree of Life is, "God is in control."
