How do we know faith can move mountains?

The sermon illustrates the concept of faith through the journey of Israel across the Jordan River, which represents the natural barriers that seem insurmountable. Just as the priests had to step into the floodwaters before seeing God’s amazing work, believers are called to act in faith, looking past their immediate circumstances. The biblical narrative demonstrates this principle repeatedly, showing how faith activates God's power. The essence of faith is in recognizing the eternal realities of God's promises, even when faced with apparent impossibilities.
