Excessive care about worldly matters is characteristic of an unbelieving and fainthearted person, and woe to us, if, in taking care of ourselves, we do not use as our foundation our faith in God, who cares for us! If we do not attribute visible blessings to Him, which we use in this life, then how can we expect those blessings from Him which are promised in the future? We will not be of such little faith. By the words of our Saviour, it is better first to seek the Kingdom of God, for the rest shall be added unto us (see Mt. 6:33).
