Because the well runs dry, we know Jesus is the river of living water (John 4).
Because the storm rages, we know Jesus is the Lord of the storms (Matthew 14).
Because the floods overwhelm, we know Jesus is the rock on which to build (Matthew 7).
Because the foundation shivers, we know Jesus is the cornerstone that will not move (Matthew 21).
Because sickness comes, we know Jesus is the healer (Matthew 4).
Because we’re bankrupt through the debt of sin, we know Jesus is our redeemer (Galatians 3).
Because we grieve, we know Jesus is the voice calling from the shore, “Friends, haven’t you any fish?” (John 21).
Because we’re full of doubt, we know Jesus is the nail-scarred palm inviting our touch (John 20).
Jesus taught in the nasty-now-and-now because he knew disciples with focused faith are never made in the classroom; we’re made in the uncertainty of life as we come face-to-face with “I can’t; but God can.” Our lives change more through the crisis we experience than through the creed we confess.
In other words, what we know first-hand of God is what takes root and changes the way we live. We change because we have believed and come to know the Holy One of God (based in John 6:69).
