Jesus Christ established the kingdom of God during his earthly ministry, setting up his spiritual other-worldly kingdom that would consume all nations and last forever. Now, for the citizens of God’s kingdom – the children of God – we are called upon to place the utmost priority on the kingdom of God. We must seek the kingdom of God first and foremost in our lives and we will experience the righteousness, joy, and peace in the Holy Ghost of the kingdom in our hearts.
