God gave the children of Israel physical signs (cloud by day and fire by night). This provided direction of where to go and comfort that God was with them. They often ignored that and displeased God, but God always provided them with hope and direction.
Today the same God guides us with His word. He provides us with direction (straight path) and a comfort to know He is there for us. Do we often ignore His word for which path to follow and displease God? We can be comforted to know He is always there for us, giving us hope and direction.
Make sure you go where God leads you. (Psalms 23)
