Jesus spoke of faith the size of a mustard seed moving tree-sized or mountain-sized challenges. What if you had to build a large barge as huge as a ship? That was Noah’s challenge. He stepped out in faith. Very little detail is given us, but that it took 120 years and was as long as 5 football fields. Too big? Naval architects and structural engineers concluded that the shape was optimal for the stresses involved. What if you were 75 years old and had to move your entire family to another country? Abraham did just that, he stepped out in faith. What if you were past child-bearing age and still wanted a family? Sarah believed that God had promised and was faithful. If it’s God’s will, it may often look like too big a challenge. Take the first step anyway.
