"We," he says, "worship by the Spirit of God." The Holy Spirit was not absent from the old economy. But in those days the consciousness and the faith of His working were dim, and the understanding of the scope of it was limited. In the times of the New Testament, on the contrary, the promise and the presence of the Spirit assume a primary place. This is the great promise of the Father which was to come into manifestation and fulfilment when Christ had gone away. This, from Pentecost onwards, was to be distinctive of the character of Christ's Church. According to the Apostle Paul, it is one great end of Christ's redemption, that we may receive the promise of the Spirit through faith. So, in particular, Christian worship is by the Spirit of God. Therefore it is a real and most inward fellowship with God. In this worship it is the office of the Holy Spirit to give us a sense of the reality of Divine things, especially of the truths and promises of God; to touch our hearts with their goodness, on account especially of the Divine love that breathes in them; to dispose us to decision, in the way of consent and surrender to God as thus revealed. He takes the things of Christ, and shows them to us. So he brings us, in our worship, to meet with God, mind to mind, heart to heart. Although all our thoughts, as well as all our desires, come short, yet, in a measure, a real consent with God about His Son and about the blessings of His Son's gospel comes to pass. Then we sing with the Spirit, when our songs are filled with confidence and admiration, arising out of a sense of God's glory and grace; and we pray in the Holy Ghost, when our supplications express this loving and thankful close with God's promises. It is our calling and our blessedness to worship by the Spirit of God. Much of our worship might fall silent, if this alone should be upheld: yet this alone avails and finds God. Whatever obscures this, or distracts attention from it, whether it be called Jewish or Christian, does not aid worship, but mars it. It is true that the presence of the Spirit of God is not discernible otherwise than by the fruits of His working. And the difficulty may be raised, how can we, in practice, be secure of having the Spirit, thereby to worship God? But, on the one hand, we know in some degree what the nature of the worship is which He sustains; we can form some conception of the attitude and exercise of soul towards Christ and God which constitutes that worship. We do therefore know something as to what we should seek; we are aware of the direction in which our face should be set. On the other hand, the presence of the Spirit with us, to make such worship real in our case, is an object of faith. We believe in God for that gracious presence, and ask for it; and so doing, we expect it, according to God's own promise. On this understanding we apply ourselves to find entrance and progress in the worship which is by the Spirit.
