To have faith as a mustard seed. How big is a mustard seed?
Pretty small, but, when it grows it flourishes. It grows and grows and grows! All you have to do is believe.
31 Another parable put he forth unto them, saying, The kingdom of heaven is like to a grain of mustard seed, which a man took, and sowed in his field:
32 Which indeed is the least of all seeds: but when it is grown, it is the greatest among herbs, and becometh a tree, so that the birds of the air come and lodge in the branches thereof.
47 Again, the kingdom of heaven is like unto a net, that was cast into the sea, and gathered of every kind:
48 Which, when it was full, they drew to shore, and sat down, and gathered the good into vessels, but cast the bad away.
49 So shall it be at the end of the world: the angels shall come forth, and sever the wicked from among the just,
50 And shall cast them into the furnace of fire: there shall be wailing and gnashing of teeth.
