Luke 17:6 (NASB)
If you had faith like a mustard seed, you would say to this mulberry tree, "Be uprooted and be planted in the sea", and it would obey you.
This verse raises two issues, we are unable to perform miracles and God's works either because we don't even have the faith of a mustard seed or because we're not exercising our faith. However, Romans 12:3 tells us that God has given each of us a measure of faith, at least the size of a mustard seed. So, our inability to perform mighty deeds for God boils down to not exercising that faith. May we all walk by faith and not by sight today.
