Doctrines Concerning

The origin, nature, and destiny of human beings

D. That Adam, the first man, deliberately chose to sin against the express Word of God as an act of
his free will, resulting in physical and spiritual death.

Gen 2:16 And the LORD God commanded the man, saying, Of every tree of the garden thou mayest freely eat:

Gen 2:17 But of the tree of the knowledge of good and evil, thou shalt not eat of it: for in the day that thou eatest thereof thou shalt surely die.

Gen 3:6 And when the woman saw that the tree was good for food, and that it was pleasant to the eyes, and a tree to be desired to make one wise, she took of the fruit thereof, and did eat, and gave also unto her husband with her; and he did eat.

Gen 3:7 And the eyes of them both were opened, and they knew that they were naked; and they sewed fig leaves together, and made themselves aprons.

Gen 3:8 And they heard the voice of the LORD God walking in the garden in the cool of the day: and Adam and his wife hid themselves from the presence of the LORD God amongst the trees of the garden.

Personal Opinion:

It just now occurs to me that Adam and Eve got into trouble not just from disobedience to God's instruction to not eat the special fruit.

The instruction was given to the man.  To me, that implies that it was his job to pass it along to the woman and he had the charge of seeing to the obedience  of his little family.

He seems to have been right on the spot when the serpent did the tempting and failed in his job of spiritual leader.
