In his farewell speech, Joshua reminds the people of Israel to live out their covenant with God passionately. They are to remain in faith and not be disobedient. Everyone in Israel followed Joshua's convictions during his lifetime, because they were attractive and compelling. He embodied the Law of Magnetism very strongly and built on it right to his final words.
Joshua 24:15 And if it seem evil unto you to serve the LORD, choose you this day whom ye will serve; whether the gods which your fathers served that were on the other side of the flood, or the gods of the Amorites, in whose land ye dwell: but as for me and my house, we will serve the LORD.
