I confess I’m not sure about the question let alone the answer. It does seem like some verses encourage that idea, “Lord increase our faith…” On the other hand our text for Sunday seems to suggest the opposite, that the size of our faith is not as important as the object of our faith. Even faith the size of a mustard seed is sufficient for overcoming any obstacle. I think the amount of our faith may be overrated while the confidence we have in God is over looked. A friend (thanks Julie P.) posted the following on FaceBook this week, "Those who trust in the Lord are like Mount Zion, which cannot be shaken but endures forever. " (Psalm 125:1) When God is the center of a kingdom or city, He makes it strong like Mount Zion, which cannot be shaken. And when God is the center of a soul, although disaster may crowd in on all sides and roar like the waves of the sea, there is constant calm within. The world can neither give nor take away this kind of peace. What is it that causes people to shake like leaves today at the first hint of danger? It is simply the lack of God living in their soul, and having the world in their hearts instead.”(--R. Leighton) Julie has had plenty to shake her life but there has been a constant calm…she’s living that reality. The psalmist didn’t refer to the amount or size of faith rather simply stated, “Those who trust in the Lord…” Those who trust in the Lord are those who are confident in Him and committed to Him and believe the promises that He has made. In a parallel account of our Matthew 17 text, the father of the boy in question said, “I believe, help me with my doubts” (Mark 9:24 MSG). I like that. The father believed to the extent he was able but confessed he needed some help. The liberation of his son from demonic bondage surely helped with that! Do we believe the Lord today? Are we confident in Him? Do we believe His promises? Do we obey Him? Do we face our adversities with His present, active assistance or turn to our own resources? Those who trust in the Lord are as strong as Mt Zion.
