It is hard for us to believe God will provide for everything, especially since He tends not to be early but waits in till the last minute to give.
I like the example he gives us in the life of Jesus. When He was an infant, not knowing enough to ask for anything, God provided for his entire family to escape the clutches of King Herod.
In Matthew 2:9-13 The Magi came to worship Jesus and left gold, frankincense and myrrh as a gift. Not long after they left an angel appeared to Joseph in a dream and told him to take Jesus to Egypt. God had just given Joseph much wealth in those days, enough to start a new life in Egypt.
Know that God loves you enough to provide for everything you need, even when you don’t know when to ask for it.
