How much faith do we need? As much as possible. But even a faith as small as a mustard seed can lead us to Christ.
Jesus said, “What is the Kingdom of God like?
To what can I compare it?
It is like a mustard seed that a man took and planted in the garden.
When it was fully grown, it became a large bush
and the birds of the sky dwelt in its branches.”
Again he said, “To what shall I compare the Kingdom of God?
It is like yeast that a woman took
and mixed in with three measures of wheat flour
until the whole batch of dough was leavened.”
We all need to pray that our faith will grow each and every day.
