Why do you reason about these things in your hearts? 

Not being weak in faith, [Abraham] did not consider his own body, already dead (since he was about a hundred years old), and the deadness of Sarah’s womb. He did not waver at the promise of God through unbelief, but was strengthened in faith, giving glory to God. § Which is easier, to say to the paralytic, “Your sins are forgiven you,” or to say, “Arise, take up your bed and walk”? § If you can believe, all things are possible to him who believes.All authority has been given to Me in heaven and on earth. § Why are you so fearful? How is it that you have no faith? § Look at the birds of the air … your heavenly Father feeds them. Are you not of more value than they? § Why do you reason among yourselves because you have brought no bread? Do you not … remember the five loaves of the five thousand?My God shall supply all your need according to His riches in glory by Christ Jesus.
