Instead of walking in the continual presence of God, I often walk within the worry and sadness of my own (and sometimes others') perceived inadequacies, failures, relationships, and losses. In doing this, I disregard the love for us that God has so abundantly revealed in his coming. By choosing to walk in worry and doubt, concerned with the people around me (and all their worries, and fears, and expectations), I also ignore his command to walk in Him, to give him all of my heart, all of my soul, and all of my mind.
Today's advent reading from Matthew 22:34-38 (when Jesus tells the Pharisees about the most important commandment), challenges me to get rid of those old worries (and to deliberately choose one...to give up forever) in exchange for the "shelter of a loved and loving God."
