4. We must notice what is implied in this passage about the Holy Trinity. St. Paul speaks[8] of 'the Spirit of God' (the Father), 'the Spirit of Christ,' 'Christ,' and then again, the 'Spirit of Him that raised up Christ,' as if all these expressions were identical; as elsewhere[9] he prays that the Father will strengthen men by His Spirit, in order that Christ may dwell in their hearts, and they be filled with the fullness of God. All which language means that where the Spirit is, Christ is, and where Christ is, God the Father is. So in St. John, our Lord speaks of the Holy Spirit as 'another' advocate who is to come 'in his name' from the Father; and yet adds that in the Spirit's coming He Himself will come; and with Him the Father--'we will come[10].' The sacred 'persons' are spoken of as distinct--personally distinct--and yet as so mutually involved in the action one of another that the coming of one is the coming of all. So truly is God one in three. We find something like this in human personalities under the influence of love. Each single personality is not {286} self-contained and exclusive. Love, to a real degree, fuses persons; and thus the husband and wife and child (to take the highest example) may be said to live and act in one another and through one another's influence. But this is only to a limited extent. We are also mutually exclusive. Our responsibility and actions remain individual and impermeable. What I am doing, I am doing, and not another. But with God the mutual interpenetration of Father, Son, and Holy Spirit, is represented in the inspired language as far more complete. The Godhead is a fellowship and relationship of perfect love 'in three persons.' But God is not three separate individuals. What each 'person' does the others do. The action of one involves all. God is inseparably one in His being and in His action. If the Father creates, He creates through the Son and by the Spirit. If the Son redeems, the redemption proceeds from the Father and is effected in the Spirit. If the Spirit sanctifies, it is from and in the Father and the Son. Thus when the Spirit came forth at Pentecost out of the uplifted manhood of the Son to impart to us all His richness, He came not merely to supply His absence, but to accomplish His presence. He makes Christ present within us, and also the {287} Father: so that God, three in one, dwells in the hearts of His people. 5. 'The requirement of the law is to be fulfilled in us.' Do we ask how we are to keep the whole of that terrible law? It is by obeying the commandment to love our neighbours as ourselves, in which the whole law is 'briefly comprehended[11].'
