The Lord gives a simple answer for Joshua to tell the priests to walk into the river, with a promise that the ground will become dry as they continue to push forward.
The task at hand seems fairly simple, just step into the water. This is where fear, pride or doubt may begin to set in but, all of us have to decide to make this same step of Faith and get our feet wet. The Lord does fulfill his promises, but like the priests, not before we are willing to act on our faith and take that first step.
I see this each day of my life. Sometimes it my seem in my mind the Lord is requiring a lot, but when I can set my pride and fears aside, I realize I am safe, making that step into the light. As we are more willing to act on our faith we will see miracles, and we'll see how truly involved the Lord is in our lives.
From this chapter, it lays out an equation of faith we can all apply to our lives..
Prayer + Obedience + Acting on Faith = Miracles
Let us all follow the example of the priests and act on our faith, no longer limiting ourselves or the Lord in the miraclesD&C 45:62, we will see each day. Make that first step, get your feet wet!
