Our lives are continually full of choices. In many cases, we choose to make no choice and thus allow others to make those decisions for us. Perhaps this is why God's path can be so difficult for us. We are asked to actually make a choice.
Even with Jesus standing among them performing miracles, many people still chose to walk away from Him. What He asked was too bizarre for them, too strange to fully comprehend. Yet His disciples continued to follow Him. When He asked why, Peter responded by asking where else would they go. Jesus holds the answers; He brings eternal life. Nothing else can compare to His promise.
