Sermons on Numbers 20
The very same hardships that God designs to grow our faith can also destroy our faith when we grow frustrated. Frustration places us in great spiritual danger because it destroys our faith in God and tempts us into unbelief. But our unbelief dishonors God and disconnects us from His divine blessing.
When faced with the holiness of God our sinful minds can lure us into self-righteousness, believing that God needs our help to accomplish His plans and will upon the earth.
