Along with the revelation of God to mankind, Jesus introduced the Kingdom idea - he disappointed some by his refusal to assume a worldly throme, but he established a spiritual kingdom of eternal value - one that is growing still, and one that is open to all. Jesus said: "where the spirit of God teaches and leads the soul of man, there in reality is the kingdom of heaven. And this kingdom of God is righteousness, peace, and joy in the Holy Spirit."
