It would seem that as written in Holy Scripture, when Adam and Eve first walked upon this good earth, all was well, until they made their fateful decision of disobedience to eat from the tree of the knowledge of good and evil, which thus changed their dynamic, dramatically. In other words, before they ate of the tree of good and evil, they knew not sin, nor were they capable of behaving in a manner that would create sin, but once they became knowledgeable, it thus meant that they were now free agents, capable of making their own decisions, good or bad, and therefore to suffer the appropriate consequences, so of.
That is to say, each of us who are here in this present domain has been provided with the power and therefore the free will to make our own decisions, and if so determined to do so, to defy God or our fellow humankind. The problem though with being willfully disobedient to God’s good Commandments is not that we are disallowed from doing so, but rather the issue is that there are consequences to be paid, for those who make decisions that are detrimental to their soul, as well as often being harmful to others, which must be corrected, because God, our God, is both just and inerrant.
That said, our God, is a God that desires the best for us, which means that when we are troubled, misguided, or confused, there is always going to be a pathway that will bring enlightenment to us if only we would dutifully follow it. That pathway is best represented by our Messiah, the Christ, who came here to liberate us from the delusions and mistakes that so often we are prone to suffer from. Indeed, whereupon there was once that tree of the knowledge of good and evil, we find that God has provided us with a new fruit from a different tree, which is the fruit that Christ so represents. So then, our option is to take and eat that fruit of Christ, and hence find redemption or to ignore such to our detriment, as per our inclination and free choice. Those though, that are sincere about finding their way back to God, and of their salvation, therein, are the very same that eat that fruit, in the recognition that by doing so they will find that eternal sanctuary that thus far has eluded them.
It must be said, that when we ponder upon God and the justice that God so represents, we have to take into fair consideration that God desires each one of us to return to the fold, and God will not rest until that so happens, which is why Christ came amongst us, to provide us with what we need to know to accomplish that very task. Those then, that eat the fruit of Christ, are the same that have been redeemed, and in that redemption, their eyes will be re-opened, knowing the important difference between good and evil, and have thereby sworn themselves to the good, forevermore.
