Jesus was not rebuking the disciples in this passage. Their faith was real, but it was disordered and unfocused, and was not at work in the important realities of life. The disciples were scattered to their own concerns and they had interests apart from Jesus Christ. After we have the perfect relationship with God, through the sanctifying work of the Holy Spirit, our faith must be exercised in the realities of everyday life. We will be scattered, not into service but into the emptiness of our lives where we will see ruin and barrenness, to know what internal death to God’s blessings means. Are we prepared for this? It is certainly not of our own choosing, but God engineers our circumstances to take us there. Until we have been through that experience, our faith is sustained only by feelings and by blessings. But once we get there, no matter where God may place us or what inner emptiness we experience, we can praise God that all is well. That is what is meant by faith being exercised in the realities of life.
