The Tree that divides rightly is the Tree of Life who is Jesus Christ, the Word of God (John Chapter 1 verses 1 through 5.)
And if we study to show ourselves approved in His Word ,
2 Timothy 2:15 KJVS
“Study to shew thyself approved unto God, a workman that needeth not to be ashamed, rightly dividing the word of truth.”
Jesus Christ helps us rightfully divide that which is good (His Word) so we can discern between good, and evil, light and darkness, clarity, and obscurity.
His Word keeps His way.
Jesus Christ is the Tree of Life, and it is His Word that sustains us unto everlasting life.
2 Timothy 2:16 KJVS
“But shun profane and vain babblings: for they will increase unto more ungodliness.”
Shun that which is profane, vain, and confusing that doesn’t line up to that which is Quick ( Alive) and Powerful.
Hebrews 4:12 KJVS
“For the word of God is quick, and powerful, and sharper than any twoedged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart.”
Through His Spirit, His Word Divides, and separates, and is a DICERNER of thoughts and the intents of the heart. (Romans Chapter 8:27.)
His Word also divides Soul, and Spirit , joints and marrow . The Word of God who is Jesus Christ separates all that is profane, vain, and confusing inside our Souls that only increases to more ungodliness. For He is a Quickening Spirit. His Word is alive ,and it is the marrow( moisture) for the Spiritual body and can prevent many from being dried out of Truth, at the Woe of the Sixth Trump when Satan appears the Antichrist( See the dry bones in Ezekiel Chapter 37.)
But we can see in Eziekiel Chapter 37 many will lose that moisture, and die Spiritually at the Woe of the Sixth Trump.
The Word of God is Jesus Christ and He is the Tree of Life, and His Truth keeps His way, and His Truth will keep many divided from outer darkness, when He returns at the Woe of the Seventh Trump.
Matthew 25:31-33 KJVS
“When the Son of man shall come in his glory, and all the holy angels with him, then shall he sit upon the throne of his glory:  And before him shall be gathered all nations: and he shall separate them one from another, as a shepherd divideth his sheep from the goats:  And he shall set the sheep on his right hand, but the goats on the left.”
So is it really us that rightfully divides the Truth or is it our Heavenly Fathers Holy Spirit ( John Chapter 14 verses 15 through 26,) through His Word (Jesus Christ) that is within us?
Partake from the Tree that rightfully divides, not from the vile tree , that can cause you to be divided from Our Lord, and His way.
Genesis 3:23-24 KJVS
“Therefore the Lord God sent him forth from the garden of Eden, to till the ground from whence he was taken.  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.”
The Sword of Truth, is what rightfully divides to keep His Way, and can, and will bring many back to that only way, which is Jesus Christ, the Tree of Life.
