The last park of the passage deals with the new conditions consequent on Christ's departure. The Twelve had been exempt from the care of providing for themselves while He was with them, but now they are to be launched into the world alone, like fledglings from the nest. Not that His presence is not with them or with us, but that His absence throws the task of providing for wants and guarding against dangers on themselves, as had not been the case during the blessed years of companionship. Hence the injunctions in Luke 22:36 lay down the permanent law for the Church, while Luke 22:37 assigns as its reason the speedy fulfilment of the prophecies of Messiah's sufferings.
Substantially the meaning of the whole is: I am on the point of leaving you, and, when I am gone, you must use common-sense means for provision and protection. I provided for you while I was here, without your co-operation. Remember how I did so, and trust Me to provide in future, through your co-operation.'
The life of faith does not exclude ordinary prudence and the use of appropriate means. It is more in accord with Christ's mind to have a purse to keep money in, and a wallet for food-stores, than to go out, as some good people do, saying, The Lord will provide.' Yes, He will; but it will be by blessing your common-sense and effort. As to the difficulty felt in the injunction to buy a sword, our Lord would be contradicting His whole teaching if He was here commanding the use of arms for the defence of His servants or the promotion of His kingdom. That He did not mean literal swords is plain from His answer to the Apostles, who produced the formidable armament of two.
It is enough.' A couple are plenty to fight the Roman Empire with. Yes, two too many, as was soon seen. The expression is plainly an intensely energetic metaphor, taking line with purse and scrip. The plain meaning of the whole is that we are called on to provide necessary means of provision and defence, which He will bless. The only sword permitted to His followers is the sword of the Spirit.
