2 Samuel 6:1-19
After he becomes king of Judah and Israel, one of David's first priorities is to bring the Ark of the Covenant back to Jerusalem. David knows that it is God's presence and work among them that will allow Israel to prosper, and one of his main roles as king is to lead them in their worship of him. What David believed, and what he wanted Israel to know, it that God's activity in our lives isn't just reserved to "sacred" moments or celebrations, and worship isn't reserved to weekly service. God is present in all of life, and we can worship him at all times.
