Matthew 6:31,32

Therefore take no thought Be no more distracted and torn in pieces, as it were, with anxious and unbelieving thoughts, Saying, What shall we eat, &c. How shall we be provided for during the remainder of our lives? For after all these things do the Gentiles seek Who are strangers to the promises of God's covenant, and to the hopes of his glory. “It was the general character of the heathen, that they prayed to their gods, and laboured themselves, for no blessings but the temporal ones here mentioned, as is plain from the tenth Sat. of Juvenal; and that because they were in a great measure ignorant of God's goodness, had erred fundamentally in their notions of religion, and had no certain hope of a future state.” See Ephesians 2:12. For your heavenly Father knoweth that ye have need of these things Your heavenly Father is far better acquainted with all your wants than you yourselves are, and does not disregard them. There is a noble antithesis in this passage. Christ sets God's knowledge of our wants in opposition to the anxiety of the heathen about having theirs supplied, to intimate that the one is much more effectual for that purpose than the other.
