back in the Garden of Eden it wasn't so much a test of obedience but an opportunity to exert his free moral agency in choosing one tree from the other and God told him what tree to choose from yet he could not choose it for him and even told him the consequences of choosing the wrong tree or eating from the wrong tree. It was actually a matter of believing God or not believing God regarding walking by sight versus walking by faith and up to this very day most Christians are still walking by sight eating from the wrong tree eating from the tree of death leading to death and all kinds of deaths instead of life.
