23. When he had seen the grace of God. By these words Luke teacheth, first, that the gospel which they had received was true; secondly, that Barnabas sought nothing else but the glory of Christ. For, when he saith that he saw the grace of God, and that he exhorted them to go forward, hereby we gather that they were well taught. And the joy is a testimony of sincere godliness. Ambition is evermore envious and malicious; so that we see many seek for praise by reproving other men, because they are more desirous of their own glory than of the glory of Christ. But the faithful servants of Christ must rejoice (as did Barnabas) when they see the gospel increase, by whomsoever God shall make his name known. And assuredly those which help one another, so that they acknowledge that all the effect which springeth thence is the work of God, will never envy one another, neither will they seek to carp [at] one another, but will, with one mouth and mind, praise the power of God.
Again, this is worth the noting, that Luke doth attribute the faith of the men of Antioch, and whatsoever was worthy [of] praise there, to the grace of God. He might have reckoned up all those virtues which might make for the commendation of men; but he comprehendeth what excellence soever was in that Church under this word grace. Lastly, we must note Barnabas’ exhortation. We have already said that Barnabas did subscribe to the former doctrine which they had embraced; but lest doctrine fall away, it is most requisite that it be thoroughly imprinted in the minds of the faithful by continual exhortations. For seeing that we have to encounter continually with so many and such strong adversaries, and our minds are so slippery, unless every man arm himself diligently, it will by and by fall away, which thing infinite numbers do show to be true by their falling away. Whereas he setteth down this manner of perseverance, that they continue with purpose of heart we are hereby taught that faith hath taken deep root then when it hath a place in the heart. Wherefore it is no marvel, if scarce one of ten of those who profess faith do stand unto the end, seeing that very few know what the affection and purpose of heart meaneth.
