The good the Spirit most desires for us is our transformation into Christ's likeness (Rom. 8:29). He desires for the affections, desires, and ambitions of the Savior to be ours. God knows that when our heart beats in rhythm with his, his greatest joys are ours. We are never richer than when we are emptied of earthly ambitions and fulfilled by Christ's desires. We are never more satisfied than when we are content with his plan for our lives. We know no greater peace than when we are confident his love hedges our lives so that nothing enters except that which makes us more like the Son whom the heavenly Father cherishes. In short, when we have no greater desire than for Jesus to be glorified in us, he grants us the desires of our heart.
