This "tree of life," was another type of Christ, as the bread and healing medicine of the church, that stands "in the midst of the paradise of God" (Rev 2:7; 22:2).
The tree of the knowledge of good and evil, was a type of the law, or covenant of works, as the sequel of the story clearly manifesteth; for had not Adam eaten thereof, he had enjoyed for ever his first blessedness. As Moses saith, "It shall be our righteousness, if we observe to do all these commandments before the Lord our God, as he hath commanded us" (Deu 6:25). But both Adam and we have touched, that is, broken the boughs and fruit of this tree, and therefore now for ever, by the law, no man can stand just before God (Gal 2:16).
Ver. 10. "And a river went out of Eden to water the garden; and from thence it was parted, and became into four heads."
This river while it abided in Eden, in the garden, it was the river of God; that is, serviceable to the trees and fruit of the garden, and was herein a type of those watering ministers that water the plants of the Lord. But observe, when it had passed the garden, had gotten without the bound of the garden, from thence it was parted, and became into four heads; from thence it was transformed, or turned into another manner of thing: it now became into four heads; a type of the four great monarchies of the world, of which Babylon, though the first in order of being, yet the last in a gospel or mysterious sense. The fourth is the river Euphrates, that which was the face of the kingdom of Babel of old. Hence note, That how eminent and serviceable soever men are while they abide in the garden of Eden, THE CHURCH; yet when they come out from thence, they evilly seek the great things of the world: one is for compassing the whole land of Havilah, where is gold; another is for compassing this, a third that, and a fourth another thing, according as you see these four heads did. Observe again, That while men abide in the church of God, there is not by them a seeking after the monarchies of this world; but when they depart from thence, then they seek and strive to be heads; as that cursed monster the pope, forsaking the garden of God, became in a manner the prince of all the earth: Of whom Tyrus mentioned by Ezekiel, was a very lively type, "Thou hast been in Eden, the garden of God; every precious-stone, [that is, doctrine,] was thy covering; as the sardius, topaz, diamond," &c., "till iniquity was found in thee" (Eze 28:13-18); till thou leftest thy station, and place appointed of God, and then thou wast cast as profane out of the mountain of God, yea, though a covering cherub. See it again in Cain, who while he continued in the church, he was a busy sacrificer, as busy as Abel his brother; but when he left off to fear the Lord, and had bloodily butchered his holy brother, then he seeks to be a head, or monarch; then he goeth and buildeth a city to preserve his name and posterity for ever (Gen 4:17).
Ver. 15. "And the Lord God took the man, and put him into the garden of Eden, to dress it and to keep it."
In this also Adam was a figure of our Lord Jesus Christ, as pastor and chief bishop of his church. "I the Lord, [saith Christ,] do keep it; I will water it every moment, I will keep it night and day" (Isa 27:3).
"And the Lord God took the man." No man taketh this honour upon him, but he that is called of God, as was Aaron. Blessed is he also that can say as the prophet Amos; "And the Lord took me [said he] as I followed the flock, and the Lord said unto me, Go, prophesy unto my people Israel" (Amos 7:15).
"To dress it and to keep it." He that is not dressed, is not kept: That is a sad judgment, That which dieth, let it die; That which is diseased, let it not be dressed, let it die of that disease. By dressing therefore I understand, pruning, manuring and the like, which the dresser of the vineyard was commanded to do, without which all is overrun with briers and nettles, and is fit for nothing but cursing, and to be burned (Luke 13:6-9; Pro 24:30-34; Heb 6:7,8).
"And the Lord commanded the man, saying, Of every tree of the garden thou mayest freely eat" (v 16).
It is God's word that giveth us power to eat, to drink, and do other our works, and without the word we may do nothing. The command gave Adam leave: "Every creature of God is good, and nothing to be refused, if it be received with thanksgiving; for it is sanctified by the word of God [by the command of the word, and by receiving of it according to the limits thereof,] and prayer" (1 Tim 4:4,5).
