Charles Spurgeon Commentary Luke 17:6

"And the Lord said, If ye had faith as a grain of mustard seed, ye would say unto this sycamine tree, Be thou rooted up, and be thou planted in the sea; and it would obey you." — Luke 17:6 (ASV)

And the Lord said, If ye had faith as a grain of mustard seed, ye might say unto this sycamine tree, Be thou plucked up by the root, and be thou planted in the sea; and it should obey you.

Now, if faith as a grain of mustard seed can do this, what cannot strong faith do? What a mercy it is for us that there is so much power in such little faith! A very small piece of dynamite can work great wonders; and within the tiniest morsel of faith, if it be no bigger than a grain of mustard seed, there lies concealed almost omnipotent force. Why do we not exercise that faith more? Nothing is impossible to him that believeth. We could blast the very strongholds of Satan with this powerful powder if we would but try it.

And the Lord said, If ye had faith as a grain of mustard seed, ye might say unto this sycamine tree, Be thou plucked up by the root, and be thou planted in the sea; and it should obey you.

Meaning that anything and everything should be possible to our faith; but we need much more of it than most of us have.

Remember how holy Bernard says, "If you have a hard task, ask God to give you a hard resolution." The diamond is difficult to cut, but it can be cut if you can find something harder. So, if a very difficult task is set for us, if we get faith that is more than equal to it, it will be accomplished. With God all things are possible, which means not only that God can do all things, but that we also can do all things when God is with us.
