Out of Mark 8:34-38, John compares the philosophies & values of this world to the one mandated by Jesus. We ask God to examine our hearts as a family like David in Psalm 139:23-24, "Search me, O God, and know my heart! Try me and know my thoughts! And see if there be any grievous way in me, and lead me in the way everlasting!" Our prayer and hope is that God would lead us toward the eternal things, the Word of God and men and women’s souls.
