Trust God to transform the smallest faith into a mighty kingdom.
The mustard tree is drought tolerant, and if we have faith even the size of a tiny mustard seed, we too can tolerate the dry times in our lives, the difficult growing seasons of a Christian. And even when we are “planted” in poor soil we can still grow, even if we only have a small amount of faith.
Incidentally, the mustard tree has many uses. Mustard trees have been found in various locations throughout the world. Even though it’s one of the smallest seeds, the trees can grow up to 20 feet tall and 20 feet wide. The tree can grow in arid, dry climates and thrive even in clay or sandy soil. It can grow in hot, dry weather or cool, wet climates.
I see the mustard seed as being symbolic of faith in that our faith can be tested in the “dry times,” the most difficult of circumstances (drought, poor soil, and in clay or sandy ground). Also, even if the tree is cut down to the trunk, it can grow back again, so the analogy is that even during times of pruning, the believer can overcome and come back stronger than ever.
