Pastor Ray primarily focuses on Romans 8 to lay out what it looks like to walk in the Spirit versus walking in the flesh. The flesh feeds off of the tree of the knowledge of good and evil and there must be a great subduing of the flesh (symbolized by Sodom and Gomorrah). We instead must feast on the tree of Life, who is Jesus.
Lot is an example of someone walking in the flesh who had no power in his flesh to confront wickedness, even within his own family. We must walk in the Spirit, which is synonymous with walking with Jesus (see Romans 8:1). Cry out for understanding and allow the Holy Spirit to draw this line of demarcation between walking in the Spirit versus walking in the flesh. (NOTE: We had some technical problems with the first minute or so of the sermon, so please read Romans 6 as you begin to listen.)
