Jesus at worship on the cross offering himself for us is the ground of our worship of him and the Father by the Spirit. The gospel provides access and foundation for approaching the throne of grace with praise on our lips. Any approach toward God apart from the mediatorial work of Christ is unacceptable. The worship of God through Christ is at one and the same time an affirmation of the perfect and sufficient mediatorial work of Christ and the rejection of any other mediator. We were created for worship, but sin has left us in idolatrous worship. The only way we can worship aright once again is through the gospel that transforms our hearts, welcomes us into the presence of God, and compels us to praise the One who is truly worthy of our worship. The cross is the solid ground of our worship.
