This is with respect to secular wisdom. Secular wisdom comes from man and ends with man. Such wisdom is distortion and half-truths.
Spiritual wisdom begins with the Lord and ends with the Lord. This wisdom is pure and perfect, reflecting the truth and light of who the Lord is and who we are in Him.
In order for us to receive the things of the Lord we have to reject the secular wisdom of the world. If we attempt to mix secular wisdom and spiritual wisdom we make a mess.
We have to turn away from the secular and turn toward the spiritual in order for the power of the spiritual to manifest in and through us.
