“Here the Apostle Peter is exhorting the people to whom he was writing to do the very selfsame thing which the Apostle Paul has in mind at the end of this Epistle to the Ephesians. ‘And beside this,’ says Peter, ‘giving all diligence, add to your faith virtue.’ But before we come to look at this in detail I want to emphasize once more the element of our activity. We must get a firm hold of this principle. We cannot hope to advance until we see this clearly. Peter does not say, ‘Hand it over to the Lord; you have nothing to do. Trust to Him, leave it to Him, He will do it for you’. What he says is, ‘Giving all diligence’. It is an exhortation to us. We have to give the matter ‘all attention’, we have to be constantly at it, we have to apply ourselves to it, to add virtue to virtue (vv. 5, 6, 7). It is not going to be added for us; we have to do it. As a man cannot be strong by merely sitting down and reading books about exercises, so the Christian will never be strong until he does what Peter bids him. He has to do this thing, it is his activity, and it is done as he becomes strong and powerful and mighty in the Lord.” David Martyn Lloyd-Jones, The Christian Soldier: An Exposition of Ephesians 6:10–20 (Edinburgh; Carlisle, PA: Banner of Truth Trust, 1977), 96–97.
