God the Father sees to our needs. He cares for us and gives us our daily bread (Mt 6:11). As His children, we don't have to worry about what we are to eat, drink, or wear (Mt 6:31). God our Father is a perfect Provider. Therefore, we have complete financial security.
However, if we aren't aware of the perfect providence of God, we may feel obligated to try to take care of ourselves, as if we were Yahweh-Yireh. Of course, we will not be able to do this satisfactorily. Thus, we will probably be frustrated and insecure.
Jesus came into this world to reveal to us God the Father. Jesus is the only Way to the Father (Jn 14:6). Jesus has made it clear that the providence of God the Father is "concrete and immediate" (Catechism, 303). If we let Him, our Father will provide for all our legitimate needs or do something even greater — for example, take us into the mystery of His Son's suffering and death. We can trust God the Father completely in life, death, after life, and forever. Trust Abba!
