It is just possible that "_all_ joy" (πᾶσαν χάραν) is meant exactly to balance "_manifold_ temptations" (πειρασμοῖς ποικίλοις). Great _diversity_ of troubles is to be considered as in reality _every kind_ of joy. Nevertheless, the troubles are not to be of our own making or seeking. It is not when we inflict suffering on ourselves, but when we "fall into" it, and therefore may regard it as placed in our way by God, that we are to look upon it as a source of joy rather than of sorrow. The word for "fall into" (περιπίπτειν) implies not only that what one falls into is unwelcome, but also that it is unsought and unexpected. Moreover, it implies that this unforeseen misfortune is large enough to encircle or overwhelm one. It indicates a _serious_ calamity. The word for "temptations" in this passage is the same as is used in the sixth petition of the Lord's Prayer; but the word is not used in the same sense in both places. In the Lord's Prayer all kinds of temptation are included, and especially the internal solicitations of the devil, as is shown by the next petition: "Lead us not into temptation, but deliver us from the tempter." In the passage before us internal temptations, if not actually excluded, are certainly quite in the background. What St. James has principally in his mind are _external_ trials, such as poverty of intellect (ver. 5), or of substance (ver. 9), or persecution (ii. 6, 7), and the like; those worldly troubles which test our faith, loyalty, and obedience, and tempt us to abandon our trust in God, and to cease to strive to please Him. The trials by which Satan was allowed to tempt Job are the kind of temptations to be understood here.[34] They are material for spiritual joy, because (1) they are opportunities for practising virtue, which cannot be learned without practice, nor practised without opportunities; (2) they teach us that we have here no abiding city, for a world in which such things are possible cannot be a lasting home; (3) they make us more Christlike; (4) we have the assurance of Divine support, and that no more will ever be laid upon us than we, relying upon that support, can bear; (5) we have the assurance of abundant compensation here and hereafter.
St. James here is only echoing the teaching of his Brother: "Blessed are ye when men shall reproach you, and persecute you, and say all manner of evil against you falsely, for My sake. Rejoice, and be exceeding glad; for great is your reward in heaven" (Matt. v. 11, 12). In the first days after Pentecost he had seen the Apostles acting in the very spirit which he here enjoins, and he had himself very probably taken part in doing so, "rejoicing that they were counted worthy to suffer dishonour for the Name" (Acts v. 41. Comp. iv. 23-30). And as we have already seen in comparing the parallel passages, St. Peter (1 Peter 1, 6) and St. Paul (Rom. v. 3) teach the same doctrine of rejoicing in tribulation.
As St. Augustine long ago pointed out, in his letter to Anastasius (_Ep._ cxlv. 7, 8), and Hooker also (_Eccl. Pol._ V. xlviii. 13), there is no inconsistency in teaching such doctrine, and yet praying, "Lead us not into temptation." Not only is there no sin in shrinking from both external trials and internal temptations, or in desiring to be freed from such things; but such is the weakness of the human will, that it is only reasonable humility to pray to God not to allow us to be subjected to severe trials. Nevertheless, when God, in His wisdom, has permitted such things to come upon us, the right course is, not to be cast down and sorrowful, as though something quite intolerable had overtaken us, but to rejoice that God has thought us capable of enduring something for His sake, and has given us the opportunity of strengthening our patience and our trust in Him.
