Matthew 10:29 & Matthew 6:26.

Matthew 10:29 Are not two sparrows sold for a penny? Yet not one of them will fall to the ground apart from the will of your Father. Matthew 6:26 Look at the birds of the air; they do not sow or reap or store away in barns, and yet your heavenly Father feeds them. Are you not much more valuable than they?  There is scarcely any sin against which our Lord Jesus more warns his disciples, than disquieting, distracting, distrustful cares about the things of this life. Take no thought for your life. Not about the length of it; but refer it to God to lengthen or shorten it as he pleases; our times are in his hand, and they are in a good hand. Not about the comforts of this life; but leave it to God to make it bitter or sweet as he pleases. Food and raiment God has promised, therefore we may expect them. Take no thought for the morrow, for the time to come. Be not anxious for the future, how you shall live next year, or when you are old, or what you shall leave behind you. If we take care about our souls and for eternity, which are more than the body and its life, we may leave it to God to provide for us food and raiment, which are less. Improve this as an encouragement to trust in God. The conclusion of the whole matter is, that it is the will and command of the Lord Jesus, that by daily prayers we may get strength to bear us up under our daily troubles, and to arm us against the temptations that attend them, and then let none of these things move us. Happy are those who take the Lord for their God, and make full proof of it by trusting themselves wholly to his wise disposal. Let thy Spirit convince us of sin in the want of this disposition, and take away the worldliness of our hearts. Matthew's commentary.
