Do you agree the heart is deceitful?
I believe that the heart, mind, and senses can be deceived. I do believe, however, that each of us is conceived with an immortal soul that "thirsts for the living God," a natural inclination toward the loving Father Who so carefully and lovingly created each of us.
I believe that the soul is either edified or corrupted through those faculties, by internal factors (desires, emotions, physiology, original sin, etc.), and external factors (life experiences, people, perceptions, etc.). We are also given a free will, to use that "information" (for lack of a better word, sorry!) to choose between God and evil; to seek the truth and attempt to live according to or against it.
I believe in Adam and Eve (sorry about the rhyme!). When God created them, and they made the wrong choice, God was both just, in casting them out of the Garden, and merciful in promising a Redeemer. I believe He gives that same consideration to everyone who honestly tries to seek the truth and follow it, even if the heart, mind, and senses have misguided it along the way.
Sorry to go on again! Thanks for asking, and God bless you!
