And besides this, giving all diligence,.... "Or upon this", as the Syriac and Arabic versions read, bestow all your labour, diligence, and care; namely, on what follows, and that from the consideration of what goes before; for nothing can more strongly animate, and engage to the diligent exercise of grace and discharge of duty, than a consideration of the high favours, and free grace gifts of God, and the exceeding great and precious promises of his Gospel:add to your faith virtue; or "with your faith", so the Arabic version renders it, and the like, in the following clauses.
They had faith, even like precious faith with the apostles, not of themselves, but by the gift of God, and which is the first and principal grace; it leads the van, or rather the "chorus", as the word rendered "add" signifies; and though it is in itself imperfect, has many things lacking in it, yet it cannot be added to, or increased by men; ministers may be a means of perfecting what is lacking in it, and of the furtherance and joy of it, but it is the Lord only that can increase it, or add unto it in that sense, and which is not the meaning here: but the sense is, that as it is the basis and foundation of all good works, it should not stand alone, there ought to be virtue, or good works along with it, by which it may be perfected, not essentially, but evidentially, or might appear to be true and genuine; for by virtue may be either meant some particular virtue, as justice towards men, to which both the grace and doctrine of faith direct; and indeed pretensions to faith in Christ, where there is not common justice done to men, are of little account; or, as others think, beneficence to men; and so the Ethiopic version renders it, "proceed to bounty by your faith"; and faith does work by love and kindness to fellow creatures and Christians; but this seems rather designed by brotherly kindness and charity, in 2Pe 1:7 or boldness, courage, constancy, and fortitude, which ought to go along with faith.
