"Joshua summoned all Israel, their elders and heads, their judges and officers, and said to them, 'I am now old and well advanced in years; and you have seen all that the Lord your God has done to all these nations for your sake, for it is the Lord your God who has fought for you. Behold, I have allotted to you as an inheritance for your tribes those nations that remain, along with all the nations that I have already cut off, from the Jordan to the Great Sea in the west. The Lord your God will push them back before you, and drive them out of your sight; and you shall possess their land, as the Lord your God promised you. Therefore be very steadfast to keep and do all that is written in the book of the law of Moses, turning aside from it neither to the right and nor to the left, that you may not be mixed with these nations left here among you, or make mention of the names of their gods, or swear by them, or serve them, or bow down yourselves to them, but cleave to the Lord your God as you have done to this day. Joshua 23: 2-8
The admonition from God to his people about staying true to the law of Moses should ring true to us today. God set forth a law so that his people would be able to tell the difference between right and wrong; the Truth and the lies of the Prince of this World. It would behoove us well to remember that.
