John Calvin Commentary Matthew 6:29

"yet I say unto you, that even Solomon in all his glory was not arrayed like one of these." — Matthew 6:29 (ASV)

Not even Solomon in all his glory. This means that the kindness of God, which is gloriously displayed in herbs and flowers, exceeds all that people can accomplish by their wealth or power, or in any other way. Believers ought to be convinced that, though all means fail, they will lack nothing necessary for their full satisfaction, provided they continue to enjoy the blessing of God alone.

O you of little faith. In this respect, Christ justly accuses us of deficiency or weakness of faith, for the more powerfully we are affected by anxiety about the present life, according to our own base views, the more we show our unbelief if everything does not happen as we wish. Many people, accordingly, who in great prosperity appear to possess faith, or at least to have a tolerable share of it, tremble when any danger of poverty presents itself.
