Remember, however, that in the New Testament these names of slave and owner are transferred to Christians and Jesus Christ. 'The Servant' has His slaves; and He who is God's Servant, and does not His own will but the Father's will, has us for His servants, imposes His will upon us, and we are bound to render to Him a revenue of entire obedience like that which He hath laid at His Father's feet.
Such slavery is the only freedom. Liberty does not mean doing as you like, it means liking as you ought, and doing that. He only is free who submits to God in Christ, and thereby overcomes himself and the world and all antagonism, and is able to do that which it is his life to do. A prison out of which we do not desire to go is no restraint, and the will which coincides with law is the only will that is truly free. You talk about the bondage of obedience. Ah! 'the weight of too much liberty' is a far sorer bondage. They are the slaves who say, 'Let us break His bonds asunder, and cast away His cords from us'; and they are the free men who say, 'Lord, put Thy blessed shackles on my arms, and impose Thy will upon my will, and fill my heart with Thy love; and then will and hands will move freely and delightedly.' 'If the Son make you free, ye shall be free indeed.'
Such slavery is the only nobility. In the wicked old empires, as in some of their modern survivals to-day, viziers and prime ministers were mostly drawn from the servile classes. It is so in God's kingdom. They who make themselves God's slaves are by Him made kings and priests, and shall reign with Him on earth. If we are slaves, then are we sons and heirs of God through Jesus Christ.
Remember the alternative. You cannot be your own masters without being your own slaves. It is a far worse bondage to live as chartered libertines than to walk in the paths of obedience. Better serve God than the devil, than the world, than the flesh. Whilst they promise men liberty, they make them 'the most abject and downtrodden vassals of perdition.'
The Servant-Son makes us slaves and sons. It matters nothing to me that Jesus Christ perfectly fulfilled the law of God; it is so much the better for Him, but of no value for me, unless He has the power of making me like Himself. And He has it, and if you will trust yourselves to Him, and give your hearts to Him, and ask Him to govern you, He will govern you; and if you will abandon your false liberty which is servitude, and take the sober freedom which is obedience, then He will bring you to share in His temper of joyful service; and even we may be able to say, 'My meat and my drink is to do the will of Him that sent me,' and truly saying that, we shall have the key to all delights, and our feet will be, at least, on the lower rungs of the ladder whose top reaches to Heaven.
'What fruit had ye in the things of which ye are now ashamed? But being made free from sin, and become the slaves of God, ye have your fruit unto holiness; and the end everlasting life.' Brethren, I beseech you, by the mercies of God, that ye yield yourselves to Him, crying, 'O Lord, truly I am Thy servant. Thou hast loosed my bonds.'
