During my personal Bible reading this morning, I read a Scripture that applies to how we should respond to the Lord's boundaries on sexual conduct, as well as to every area of life.
The fear of the Lord is the beginning of wisdom,
and the knowledge of the Holy One is insight. ~~Proverbs 9:10 (ESV)
We question, disregard or defiantly disobey the Lord because we neither respect His authority nor know Him enough to appreciate His wisdom and holiness. Fear, which manifests itself as healthy respect for His authority, understands that He alone has the right to determine how we handle our sexuality. Furthermore, He has no obligation to explain His reasons. Although we can discern some reasons because He kindly makes them apparent, we best honor Him by trusting Him enough to obey even if we don't understand.
