Take My yoke upon you…For My yoke is easy, and My burden is light. – Matthew 11:29, 30

He who is a Christian will not find rest in being idle. There is no unrest greater than that of the sluggard. If you would rest take Christ’s yoke, be actively engaged in His service. As the bullock has the yoke put upon its neck and then begins to draw, so have the yoke of Christ put on your neck and commence to obey Him. The rest of heaven is not the rest of sleep; they serve Him day and night in His temple. They are always resting, and yet, in another sense, they rest not day nor night. Holy activity in heaven is perfect rest. True rest to the mind of the child of God is rest on the wing, rest in motion, rest in service, not rest with the yoke off, but with the yoke on. We are to enter upon this service voluntarily; we are to take His yoke upon us voluntarily. You observe, it does not say, “Bear My yoke when it is laid upon you but take it.” Do not need to be told by the minister, “My dear brother, such-and-such a work you are bound to do,” but take up the yoke of your own accord. Do not merely submit to be the Lord’s servant but seek His service. Ask, “What can I do?” Be desirous to do it voluntarily, cheerfully, do all that lieth in you for the extension of His kingdom who has given you rest, and you shall find that the rest of your soul shall lie in your doing all you can for Jesus.

Now the burden of Christ is His cross, which every Christian must take up. Expect to be reproached, expect to meet with some degree of the scandal of the cross, for the offence of it never ceases. Persecution and reproach are a blessed burden; when your soul loves Jesus it is a light thing to suffer for Him, and therefore never, by any cowardly retirement or refusal to profess your faith, evade your share of this honorable load. Woe unto those who say, “I will never be a martyr.” No rest is sweeter than the martyr’s rest. ~ C.H. Spurgeon
