The latter is based upon the transformation based on Romans 12:1-2 and the spiritual growth that comes from feeding the born again spirit the word of God
I always learn something when I discuss scripture with you! So, let’s discuss......
Let’s look at Romans 12:1-2:
I beseech you therefore, brethren, by the mercies of God, to present your bodies a living sacrifice, holy, acceptable to God, which is your spiritual service. And be not fashioned according to this world: but be ye transformed by the renewing of your mind, that ye may prove what is the good and acceptable and perfect will of God.
Romans 12:1-2 - https://www.biblegateway.com/passage?search=Romans 12:1-2&version=ASV
Our bodies are definitely a “living sacrifice.” However, our soul which houses our mind (will and emotions) is to grow and even metamorphosis into a new creation- like a caterpillar to a butterfly......simply by the Word and Spirit of God ALONE - No man intervention.
