If you do, you do.
And the apostles said to the Lord, “Increase our faith.” So the Lord said, “If you have faith as a mustard seed, you can say to this mulberry tree, ‘Be pulled up by the roots and be planted in the sea,’ and it would obey you.
Do you feel like you need more faith? Then you don’t understand faith. “God, I need more faith” and the answer is “no, you don’t.” You just need faith. Faith is small, it is the tiniest thing, and it can move mountains (or mulberry trees).
You don’t need much of it, if you do have it, then you have enough of it. If you believe at all, nothing is impossible for God through you.
