Jot and tittle time...
There is nothing in Scripture that says there was death IN THIS PRESENT CREATION before the fall. There was plenty of physical deaths in the prior creations. Creations that were destroyed and replaced. We live in the most current creation. There will be two more to follow.
Not sure your gap theory moves the discussion any further, but quibble noted. Still, as you put it there is nothing in scripture to say there was death before the fall, and there is nothing to say that there wasn't. Which at very least tells us scripture is silent on the subject and there is no reason to find a problem with the scientific evidence.
Before Adam's fall Satan understood what death meant. That is one reason why he tempted Adam. I would assume that Satan was most expecting a physical death of the man and woman. He was expecting to take back his place as ruler of this world for himself. He was in for a gigantic surprise when Adam and Eve remained physically alive after their fall. He most likely saw God as being a liar when these (spiritually dead) folks scrambled to dress themselves in fig leaves. Physically dead creatures do not do that.
So God gave Adam a warning which Satan could understand and manipulate, but the person who needed the information, Adam, had no idea what death meant?
God created mankind just like we are.
Not quite. What God created had no defect. No sin nature. Perfect health.
You are assuming God's creation would be defective if he didn't make it the way creationists want. God tells us he provides prey for hungry ravens and lion cubs, is God's provision defective? Incidentally these references are found in two creation account Job 38 and Psalm 104, which tells us death and predation, the whole vibrant array of life we see in the natural world are part of God's creation, and in God's view, good.
So why did Eve steal the fruit? Genesis describes her being led by her fleshly desires just like we are. Gen 3:6
When the woman saw that the tree was good for food, and that it was a delight to the eyes, and that the tree was desirable to make one wise, she took from its fruit and ate; and she gave also to her husband with her, and he ate. How is this any different from 1John 2:16
For all that is in the world, the lust of the flesh and the lust of the eyes and the pride of life, is not of the Father but is of the world.
That refers to the TYPE of body we (the church) have now, in contrast to what type of body we will receive at the resurrection.
Not just the church but all of humanity, flesh and blood, perishable. The thing is Paul associates this body with God's original creation, not the fall. As shernren points out, the verse Paul quotes comparing the two natures is a verse describing Adam's creation 1Cor 15:45
Thus it is written, "The first man Adam became a living being"; the last Adam became a life-giving spirit. He talks of Adam being 'from the earth', a reference to God forming Adam from the clay. He goes on to say we are like the man of dust God formed from the earth 1Cor 15:47
The first man was from the earth, a man of dust; the second man is from heaven. 48 As was the man of dust, so also are those who are of the dust, and as is the man of heaven, so also are those who are of heaven. Really, Paul seem blissfully unaware God created Adam immortal and that this all cahnged with the fall.
1 Corinthians 15:38-40
"But God gives it a body as he has determined, and to each kind of seed he gives its own body. All flesh is not the same: Men have one kind of flesh, animals have another, birds another and fish another.There are also heavenly bodies and there are earthly bodies; but the splendor of the heavenly bodies is one kind, and the splendor of the earthly bodies is another."
Note what the verse you quotes says,
God gives it a body as he has determined. The sort of body God gave man was his choice, it is not up to you to say his choice is defective.
Man was created 'able' not to die physically. Man lost that ability in the fall.
It doesn't say we were created able not to die. Man was able not to die but it was because he was put in a garden with a tree of Life. Thrown out of the garden with no access to everlasting life, his body did what came naturally, it grew old and died. There is no suggestion in the account of any other form of immortality available to mankind.
The Tree of Life would have been given at a point of maturity that God desired of man to have, forever. But? Adam could only have received everlasting life if he ate (without sin). That is a life with a beginning, that will never end. In contrast. We are now given Eternal life. We will have life with no beginning, nor end. For our unique life will be IN GOD.
Yet we see the Tree of Life in the Book of Revelation, promised to those who conquer in the church in Ephesus, and growing on either side of the river of life in the New Jerusalem. There seems to be more to this symbol than the mere promise of everlasting life.
However you see the Tree as able to give Adam everlasting life, but not the Eternal life that is ours in the Resurrection. If the tree could give Adam everlasting life, then Adam didn't have everlasting life already, in other words, he was created mortal.
Adam's physical death was a result of the fall. Adam took on defect (the sin nature) at his fall. That defect demanded that he be denied the Tree of Life by God.
So the defect that came with the fall was being a sinner, not being mortal, and it was only a secondary effect of the fall that his sin cut his mortal body off from the one answer to its own mortality, the Tree of Life.
God is holy. He can not tolerate imperfection. Just like brain cells die when deprived oxygen, the perfection of Adam died when he was cut off from his spiritual life with God. We breathe our spiritual life with God. God exhales truth. We inhale. We then exhale faith. That is why the Word of God is "God breathed." God would not allow for the imperfection of fallen Adam to live forever. Adam and Eve were therefore refused the Tree of Life. God had a plan to replace the imperfection with perfection.
I don't get where you think Adam was created immortal, but was also given a Tree of Life in the garden that can give him immortality?
That issue was dealt with almost immediately after the fall. God's redemption plan was already in motion. For it took the shedding of blood for God to provide the animal skins to clothe Adam and Eve. Through out the Old Testament the shedding of blood was the symbolic teaching tool that pointed to the death of Christ in our place.
God knew the hearts of Adam and Eve. God saw their repentance. God therefore, provided for their salvation. God made also sure that this account was to be recorded in God's Word so we can learn from it the nature and heart of God.
In Christ, GeneZ
It always was about the cross. That is the only tree that can give eternal life. I like that fact that the cross was God's plan all along, before the fall, before the foundation of the world.
