The “tree” (6086) of “life” (2425b) is a pan-Biblical concept. It starts in the Garden. Two trees are named, Life and Knowledge. Adam sinned by eating from the tree of the knowledge of good and evil. The tree of life was not banned. He could have eaten of it at any time until he sinned, but he did not. After he sinned he and Eve were removed from the garden lest they eat of the tree of life. They were no more qualified to eat it and live forever.
We are again offered the tree of life. Here it is in the context of Wisdom. It is a beautiful promise.
Later we have the promise renewed.
(Revelation 2:7 KJV) 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.So? You can only come to know the wisdom of God through knowing Jesus. Even then you must “retaineth” (hold fast NASB) (2388/8551) according to this verse or “overcome” as it says in Revelation. That is the daily walk. Today, think about how you could better walk the walk.
