When the apostles ask Jesus to increase their faith, what are they requesting? A related passage in Habbakuk reads, “The just shall live by his faith (Heb.emunah). This word has a cluster of meanings: trust, belief, persistence, fidelity or faithfulness. By examining the times in which Habbakuk lived (not much different from ours) we can come to a better understanding of what it means for us to live by His faithfulness.
