416. The Lord's kingdom is the neighbor to which we are to give the highest level of our love, because the Lord's kingdom means the church across the entire world, also known as "the communion of saints. " It includes heaven as well.

People who love the Lord's kingdom love all in the whole world who acknowledge the Lord, have faith in him, and have goodwill toward their neighbor; they also love all who are in heaven. People who love the Lord's kingdom love the Lord above all else. They have more love for God than others do. This is because the church in the heavens and on earth is the Lord's body. They are in the Lord and the Lord is in them. Loving the Lord's kingdom, then, is fully loving their neighbor. People who love the Lord's kingdom not only love the Lord above all else; they also love their neighbor as themselves. Love for the Lord is a universal love. It affects every aspect of spiritual life and also every aspect of earthly life. This is because love for the Lord dwells in the highest reaches of us, and things at the top flow into things lower down and bring them to life in the same way that our will flows into all our intentions and actions, and our intellect flows into all our thoughts and conversations. Therefore the Lord says,

Seek first the kingdom of the heavens and its justice. Then all these things will be added to you. (Matthew 6:33)

The kingdom of the heavens is the Lord's kingdom, as the following passage in Daniel shows:

Behold, there was someone coming with the clouds of heaven - someone like the Son of Humankind. He was given dominion, glory, and a kingdom. All people, nations, and tongues will worship him. His dominion is a dominion of an age that will not pass and his kingdom is one that will not perish. (Daniel 7:13-14)
