God gave his creation a negative makeover:
-- Poison ivy, datura, and several fruit seeds are able to kill us. Cactus and roses developed thorns.
-- Indescribable pain in giving birth.
-- Man dies.
-- Man is born with the sin nature that came onto the world at its original sin. We can no longer not sin, until God gives us new birth.
The Bible teaches this about the curse...
Gen 3:16 Unto the woman he said, I will greatly multiply thy sorrow and thy conception; in sorrow thou shalt bring forth children; and thy desire shall be to thy husband, and he shall rule over thee.
Gen 3:17 And unto Adam he said, Because thou hast hearkened unto the voice of thy wife, and hast eaten of the tree, of which I commanded thee, saying, Thou shalt not eat of it: cursed is the ground for thy sake; in sorrow shalt thou eat of it all the days of thy life;
Gen 3:18 Thorns also and thistles shall it bring forth to thee; and thou shalt eat the herb of the field;
Gen 3:19 In the sweat of thy face shalt thou eat bread, till thou return unto the ground; for out of it wast thou taken: for dust thou art, and unto dust shalt thou return.
Gen 3:20 And Adam called his wife's name Eve; because she was the mother of all living.
Gen 3:21 Unto Adam also and to his wife did the LORD God make coats of skins, and clothed them.
Gen 3:22 And the LORD God said, Behold, the man is become as one of us, to know good and evil: and now, lest he put forth his hand, and take also of the tree of life, and eat, and live for ever:
Gen 3:23 Therefore the LORD God sent him forth from the garden of Eden, to till the ground from whence he was taken.
There is not a single word there about "Inherited Original Sin."
Abel was able to obey God and was righteous.
Heb 11:4 By faith Abel offered unto God a more excellent sacrifice than Cain,
by which he obtained witness that he was righteous, God testifying of his gifts: and by it he being dead yet speaketh.
God advised Cain to do what is right in RULING OVER SIN...
Gen 4:6 And the LORD said unto Cain, Why art thou wroth? and why is thy countenance fallen?
Gen 4:7 If thou doest well, shalt thou not be accepted? and if thou doest not well, sin lieth at the door. And unto thee shall be his desire, and thou shalt rule over him.
Cain rejected that advice and murdered his brother...
Gen 4:8 And Cain talked with Abel his brother: and it came to pass, when they were in the field, that Cain rose up against Abel his brother, and slew him.
Sin is a choice not an inherited disease.
The following is speaking of "by way of example" not some kind of inherited flesh malady...
Rom 5:17 For if by one man's offence death reigned by one; much more they which receive abundance of grace and of the gift of righteousness shall reign in life by one, Jesus Christ.)
Rom 5:18 Therefore as by the offence of one judgment came upon all men to condemnation; even so by the righteousness of one the free gift came upon all men unto justification of life.
Rom 5:19 For as by one man's disobedience many were made sinners, so by the obedience of one shall many be made righteous.
Many were made sinners by Adam through example. When we sinned we identified with the methodology of Adam through the exercise of our free will. That is why we are responsible.
Many are made righteous by Jesus Christ through example by identifying with Jesus Christ and WALKING in the Spirit of His life. It is a REAL MANIFEST REALITY. Jesus Christ came to this physical world and revealed the genuine righteousness of God apart from the law. Those who submit to his doctrine are made righteous for real.
That is why real Christian's don't need some silly MAGIC SWAP religion. We experience the real power of God and the real victory that goes with it. The Magic Swap religion is one of arguing for an ongoing cloak for defeat.
