God works in partnership with His people. Everything God does in this world is through the agency of other people. Israel was given the land, but they still had to do what God said in order to conquer it. God keeps His promises to His people, and that includes us! If you have faith in Christ, then you are one of His people, and that means that all the promises of God will be fulfilled in your life! Our Father has never broken a promise, and therefore we have hope!
