People generally pass over that 'Therefore' which begins my text, but it is full of significance and of importance. It links the precept which we have been considering with the immediately preceding hope which the Apostle has so triumphantly proclaimed, when he says that 'we look for the Saviour from heaven, the Lord Jesus Christ, who shall change the body of our humiliation that it may be fashioned like unto the body of His glory, according to the working whereby He is able even to subdue all things to Himself.' So there rises before us that twofold great hope; that the Master Himself is coming to the succour of His servants, and that when He comes, He will perfect the incomplete work which has been begun in them by their faith and steadfastness, and will change their whole humanity so that it shall become participant of, and conformed to, the glory of His own triumphant manhood. That hope is presented by the Apostle as having its natural sequel in the 'steadfastness' of my text, and that 'steadfastness' is regarded by the Apostle as drawing its most animating motives from the contemplation of that great hope. Blessed be God! The effort of the Christian life is not one which is extorted by fear, or by the cold sense of duty. There are no taskmasters with whips to stand over the heart that responds to Christ and to His love. But hope and joy, as well as love, are the animating motives which make sacrifices easy, soften the yoke that is laid upon our shoulders, and turn labour into joy and delight. So, dear brethren, we have to set before us this great hope, that Jesus Christ is coming, and that, therefore, our labour on ourselves is sure not to be in vain. Work that is done hopelessly is not done long, and there is no heart in it whilst it is being done. But if we know that Christ will appear, 'and that when He who is our life shall appear, we also shall appear with Him in glory,' then we may go to work in keeping ourselves steadfast in Him, with cheery hearts, and with full assurance that what we have been doing will have a great result. You have read, no doubt, about some little force in North-West India, hemmed in by enemies. They may well hold out resolutely and hopefully when they know that three relieving armies are converging upon their stronghold. And we, too, know that our Emperor is coming to raise the siege. We may well stand fast with such a prospect. We may well work at our own sanctifying when we know that our Lord Himself--like some master-sculptor who comes to his pupil's imperfectly blocked-out work, and takes his chisel in his hand, and with a touch or two completes it--will come and finish what we, by His grace, imperfectly began. 'So stand fast in the Lord,' because you have hope that the Lord is about to come, and that when He comes you will be like Him. One last word. That steadfastness is the condition without which we have no right to entertain that hope.
