True saints center their attention on Christ, and His beauty transcends all others. His delight is the source of all other delight. He in Himself is best among ten thousand, and altogether lovely. These saints delight in the way of salvation through Christ because it demonstrates God’s perfection and wonder. They enjoy holiness, while they take no pleasure in sin. God’s love is a sweet taste in their mouths, regardless of whether their interests are met or not. They rejoice over all that Christ has done for them, but that is not the deepest root of their joy. No, they delight merely because God is God. And only then does our delight spill over onto all God’s works, including our own salvation.
The authentic inner essence of worship is being satisfied with Christ, prizing Christ, cherishing Christ, treasuring Christ. This is tremendously relevant for understanding what our worship services should be about. They are about going hard after God. When we say that what we do on Sunday mornings and evenings is “go hard after God”, we mean that we’re going hard after satisfaction in God. We’re seeking God as our prize, as our treasure, our soul food, our heart delight, our spirit’s pleasure; or, to put Christ in His rightful place, it means that we’re going hard after all that God is for us in Jesus Christ, crucified and risen.
