Day after day we're going to have to face challenges and circumstances that aren't beyond our power, and it's in those instances where we're going to have to use the tools god gives us.
Jesus encourages us to have faith; the assurance and belief about what we don't see yet, but that we believe it will happen. This is not just of what God can do, but about what we think He can do. Jesus taught that they'd have faith like a mustard seed, they would say to a mountain, "Step place to place, and it shall pass away; and nothing shall be impossible for you.
Let us be confident and announce the promises of God to every mountain that confronts us, whether it be discouragement, unbelief, anxiety, etc.
God is calling us to live by faith and God is calling us to believe Him. How are we going to respond to his call?
