The Lordship of Jesus Christ
Our allegiance to Christ is rarely tested in modern American culture as it is on Sunday. When we say no to the world and all of its offerings on the first day of the week, we are demonstrating the lordship of Christ not just in a general sense but in a very personal way. We are telling the world that Jesus is our Lord, that His reign extends into our very lives. Because Jesus has died and has risen from the grave for us, we are eternally His. His glory is our passion and His Word is our rule. The consequence is a radically different set of priorities that pushes back against the values of the world. While Jesus has called us to be in the world but not of the world, He does call us to separate ourselves from it on Sunday.
Our Citizenship in Heaven
When we rest from the world and worship our triune God on Sunday, we are showing the world that our citizenship is in heaven. This world is not our home. We are sojourners here, living under the reign of our King in heaven, whose glorious return we await. We are not just a countercultural people but a kingdom people at war with the god of this age and at odds with the corruption of the world. When the church gathers on the Lord’s Day, heaven itself is breaking in to the darkness in which we live and the light of Christ is made manifest. What we do on Sunday as Christians is a testimony to what we live for as well as to what we call home.
The Passing of the World
By rejecting the perverted priorities, the busyness, and the chaos of the world on Sunday, we are testifying to the passing of this world. This world, with all of its desires, is passing away. The temporal will pass into the eternal; the temptations will be swallowed up in righteousness when Christ returns. As Christians, we live not for the here and now but for what awaits us in the future. We keep the Sabbath because we cannot keep the world. It does not last. Each day, the world is giving way to corruption and corrosion while the kingdom of God remains uncorrupted.
Our Need for Grace
When we gather with the saints on Sunday, we are admitting that we remain a people in need of God’s grace. We are not yet free from sin and corruption ourselves. As we rest from work and the world, we are seeking rest for our souls, which continue to struggle with sin. On Sunday, we shut our ears to the world and listen to the Word of God preached. We confess our sins, rejoice in our salvation, and sing the praises of our Maker and Redeemer. We cannot afford to put the world and its agendas before Christ and His call to His people to gather, for in the gathering the means of grace are offered in a concentrated form for us sinner-saints.
What we do with Sunday matters. It will either be the day set aside by God for His people to rest and worship in a way that shows their distinction from the world, or it will be just another day of the week, no different from any other.
