What kind of tree did Eve eat from?
The tree was unique, the only one of its kind and was called ‘the tree of the knowledge of good and evil’.
Genesis 2:9 And out of the ground the LORD God made every tree grow that is pleasant to the sight and good for food. The tree of life was also in the midst of the garden, and the tree of the knowledge of good and evil.
Genesis 2:15 Then the LORD God took the man and put him in the garden of Eden to tend and keep it. 16 And the LORD God commanded the man, saying, "Of every tree of the garden you may freely eat; 17 "but of the tree of the knowledge of good and evil you shall not eat, for in the day that you eat of it you shall surely die."
Genesis 3:6 So when the woman saw that the tree was good for food, that it was pleasant to the eyes, and a tree desirable to make one wise, she took of its fruit and ate. She also gave to her husband with her, and he ate. 7 Then the eyes of both of them were opened, and they knew that they were naked; and they sewed fig leaves together and made themselves coverings.
The fruit of the tree altered their physiology making them like God and his angels in ‘the knowledge of good and evil’ which they were not yet equipped to handle. God could not let them live forever in that condition so he had to expel them from the garden to prevent them eating the fruit of the tree of life, which would give them eternal life.
Genesis 3:22 Then the LORD God said, "Behold, the man has become like one of Us, to know good and evil. And now, lest he put out his hand and take also of the tree of life, and eat, and live forever" — 23 therefore the LORD God sent him out of the garden of Eden to till the ground from which he was taken. 24 So He drove out the man; and He placed cherubim at the east of the garden of Eden, and a flaming sword which turned every way, to guard the way to the tree of life.
We might reasonably suppose that the garden and the two trees were destroyed in the great flood.
God’s promise of eternal life is now offered as a free gift to those who will believe and obey the Gospel preached by Jesus Christ and his apostles.
Romans 6:23 For the wages of sin is death, but the gift of God is eternal life in Christ Jesus our Lord.
2 Timothy 1:7 For God has not given us a spirit of fear, but of power and of love and of a sound mind. 8 Therefore do not be ashamed of the testimony of our Lord, nor of me His prisoner, but share with me in the sufferings for the gospel according to the power of God, 9 who has saved us and called us with a holy calling, not according to our works, but according to His own purpose and grace which was given to us in Christ Jesus before time began, 10 but has now been revealed by the appearing of our Savior Jesus Christ, who has abolished death and brought life and immortality to light through the gospel, 11 to which I was appointed a preacher, an apostle, and a teacher of the Gentiles.
Those who obey the Gospel will be raised from the dead to eternal life when Christ returns.
I hope you find this helpful.
