We as humans always think about something. Initially, when Adam and Eve were created, their thoughts were mostly about what to eat, or where to sleep. But a lot has changed since then. When man ate from the Tree of the Knowledge of Good and Evil, their thoughts changed. Their way of thinking became full with evil intentions, with an evil heart. However, Jesus came with the opposite state, with a pure heart, completely different from Adam. Now we have a choice to obtain that same pure heart!
The human body consists of blood, flesh, and bones. I think everyone understands what the body is. But where exactly does sin live? Does sin live in the body? The body is a vessel. Inside of this vessel, inside of the flesh, is a spiritual being!
Jesus said, “For from within, out of the heart of men, proceed evil thoughts, adulteries, fornications, murders, thefts, covetousness, wickedness, deceit, lasciviousness, an evil eye, blasphemy, pride, foolishness: All these evil things come from within, and defile the man.” (Mark 7:21-23)
