It does not need to be an either / or proposition.
Luke 10:27 King James Version (KJV)
27 And he answering said, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy strength, and with all thy mind; and thy neighbour as thyself.
Deuteronomy 12:32, Proverbs 30:6, Revelation 22:18, Deuteronomy 4:2
Of course, renewing of the MIND is an outcome of growing in grace and knowledge of the Lord. Resources should always be subject to the truth of the Word of God. If it is extra-special understanding and contradicts the Bible it is not good for renewing. However, that information can help understand thoughts that influence people like these two men. But it isn’t Truth if it doesn’t agree with scripture. A problem with UN-regenerate intellectuals is they elevate their thoughts and lower God’s Word.
