A Stair but Not the Whole Staircase

How do you know when to make a move? When to take that step and just do “it,” whatever “it” happens to be? It can be hard to know when to do “it,” especially when you’re trying to discern God’s will if He indeed wants you to do “it.” God will often show you a stair, to reassure you to move towards "it," but He may not show you the whole staircase. To take the stair is trust Him, even though you can't see the whole staircase.
