The Prophet Isaiah told Hezekiah, "Set thine house in order; for thou shalt die, and not live." God gave Hezekiah a warning that he was going to die and that he needed to set things in order. We all have an appointment with death, but we do not know when that appointment will be. We must get our hearts right with God and keep it that way so that we are ready when it is our time. Hezekiah prayed and God extended his life by 15 years. By setting your house in order and making things right with God, you can experience eternal life in Heaven.
