In John 4, we find the powerful account of the healing of the nobleman's son, an event full of certainty. We were introduced to a certain nobleman with a desperate need, a certain Saviour with undeniable authority, and a certain miracle that proved the power of believing without seeing. These truths still speak to us today: when we bring our burdens to Christ in faith, we can trust in the certainty of who He is and what He can do.
