Number 20:11. . .”Then Moses raised his arm and struck the rock twice with his staff.”
Remember Moses? The great leader of the OT who led the House of Israel out of bondage in Egypt. Kind of similar to what Jesus did when He revealed Himself in the NT. He leads anybody out of their bondage to sin and the world (which is our Egypt) and into the promised land which is our calling and ministry in life given to us by the Lord Himself
Of course we have to go through a wilderness during a few years while we grow and mature in our faith until we get to where He wants us to be before He can reveal His plan to us. And our calling is similar to Moses and Jesus.
We are called to be salt and light to those around us and lead them to faith in the Lord so they can be delivered from their sin and live the righteous life that God desires.
