FAITH AND AN ELEVATOR
If I stand on the ground floor of a 27-floor building and press the button for an elevator, I am confident (I have faith) that the elevator will arrive. Indeed, it does, and the door opens.
I am now presented with a vehicle that, I am confident (I have faith), will take me to the top of that building, provided I step into it. When I do, my faith in that elevator takes the form of personal trust.
I step into it, and it does the rest. My faith in the elevator does not empower the elevator, it trusts in the elevators power to take me to the floor I want to go to.
Faith is simply stepping into Christ, trusting in His power to save me.
