Jesus used small things to teach larger lessons more easily such as if God clothes the fields with lilies how much more will He clothe you. Then also God feeds the birds so that is an example that He will feed you.
28 And why are you anxious about clothing? Consider the lilies of the field, how they grow: they neither toil nor spin,29 yet I tell you, even Solomon in all his glory was not arrayed like one of these.30 But if God so clothes the grass of the field, which today is alive and tomorrow is thrown into the oven, will he not much more clothe you, O you of little faith?
