David Grabbe, asserting that the parable of the leaven hidden in the meal and the parable of the treasure hidden in the field serve as the juxtaposition of a negative and positive symbol (respectively, leaven and treasure), identifies a stark contrast between evil corruption and godly treasure, hidden for totally different reasons. Jesus never intended the church be hidden from the world, but instead that if should serve as a light or a city on a hill. This public display would occur after His death and resurrection up until His Second Coming. The superior wisdom of God, more valuable than gems and precious metals, has been hidden from the world at large, but given to chosen or called-out-ones solely at the discretion of God the Father. It is this hidden godly wisdom which enables God's saints to counteract the hidden leaven of corrupt doctrine. Wisdom that inspires an iron-clad faith (like the Centurion's) is more precious than gold which perishes. This kind of faith, belief, and trust is meaningful and valuable to our Creator.
Sometimes, we tend to make things a bit too theological and difficult, wanting to know all the facets and permutations of a doctrine, but when it comes down to the nitty-gritty of faith, it is trusting Him, taking God at His word and believing it.
In the healing of the centurion's servant, Jesus commends the centurion for his faith. This Roman officer seems to have understood an aspect of God's authority and power that even most Israelites never realized. Martin Collins contends that many Christians today still do not fully comprehend the power of God's Word.
The healing of the centurion's servant is significant in that it is one of only two miracles that Jesus did for Gentiles, and He is especially taken with the Roman officer's faith. Martin Collins shows that, along with his faith, the centurion also shows great compassion and humility, so rare even among Israelites.
How important is faith? What is the faith God requires us to have? Pat Higgins explains that faith is simple in concept, but difficult to display in our lives. Nevertheless, we must exercise this gift of God to pass the tests that are sure to precede the return of Christ.
