Satisfied as to their true Christian character, Barnabas sets himself to help them to grow. Now, remember how recently they had been converted; how, from their Gentile origin, they can have had next to no systematic instruction; how the taint of heathen morals, such as were common in that luxurious, corrupt Antioch, must have clung to them; how unformed must have been their loose Church organisation--and remembering all this, think of this one exhortation as summing up all that Barnabas had to say to them. He does not say, Do this, or Believe that, or Organise the other; but he says, Stick to Jesus Christ the Lord. On this commandment hangs all the law; it is the one all-inclusive summary of the duties of the Christian life. So, brethren and fathers, I venture to take these words now, as containing large lessons for us all, appropriate at all times, and especially in a sermon on such an occasion as the present. We may deal with the thoughts suggested by these words very simply, just looking at the points as they lie--what Barnabas _saw_, what he _felt_, what he _said_. I. What Barnabas saw. The grace of God here has very probably the specific meaning of the miracle-working gift of the Holy Spirit. That is rendered probable by the analogy of other instances recorded in the Acts of the Apostles, such as Peter's experience at Caesarea, where all his hesitations and reluctance were swept away when 'the Holy Ghost fell on them as on us at the beginning, and they spake with tongues.' If so, what convinced Barnabas that these uncircumcised Gentiles were Christians like himself, may have been their similar possession of the visible and audible effects of that gift of God. But the language does not compel this interpretation; and the absence of all distinct reference to these extraordinary powers as existing there, among the new converts at Antioch, may be intended to mark a difference in the nature of the evidence. At any rate, the possibly intentional generality of the expression is significant and fairly points to an extension of the spiritual gifts much beyond the limits of miraculous powers. There are other ways by which the grace of God may be seen and heard, thank God! than by speaking with tongues and working miracles; and the first lesson of our text is that wherever that grace is made visible by its appropriate manifestations, there we are to recognise a brother. Augustine said, 'Where Christ is there is the Church,' and that is true, but vague; for the question still remains, 'And where _is_ Christ?' The only satisfying answer is, Christ is wherever Christlike men manifest a life drawn from, and kindred with, His life. And so the true form of the dictum for practical purposes comes to be: 'Where the grace of Christ is visible, there is the Church.'
