The Lord Himself goes before you and will be with thee, He will not back down from you and will not leave thee, be not afraid and no courage "(Deuteronomy 31: 8). I believe: how God was at that time to his people, so he applied to the us, because the Old Testament is a way for us. Before we will enter in the future, "there is a God would go before us". Had it tomorrow. He is God of our future.
