In this sermon Taking On A Spirit's Nature, throughout the word we see the contrast between beasts, and saints of God. Man was compared to beasts in the old covenant before Jesus Christ came. The reason man was compared to beasts was the fate of RETURNING TO DUST as the beasts do. This was never meant to occur with Adam. But after he sinned, God said he was dust and would return to dust in a very condescending manner.
Some feel Adam was meant to physically die before he sinned. Why would God speak so condescendingly about returning to dust if it was his original fate? And death came to man by sin (Rom 5:12). Death was intended to occur with creatures, though without anything to do with sin. But not man. So, if returning to dust makes one comparable to a beast, then we see that the fall of man caused mankind to come into this low estate. If returning to dust makes us like beasts, then what is it when the RESURRECTION OF JESUS CHRIST occurs to people who were dead in sins but can present themselves alive from the dead unto God?
