So Jesus said to the Jews who had believed him, “If you abide in my word, you are truly my disciples, and you will know the truth, and the truth will set you free.” They answered him, “We are offspring of Abraham and have never been enslaved to anyone. How is it that you say, ‘You will become free’?” Jesus answered them, “Truly, truly, I say to you, everyone who practices sin is a slave to sin. The slave does not remain in the house forever; the son remains forever. So if the Son sets you free, you will be free indeed (John 8:31-36).
Our Lord declares to the Jews in one comprehensive sentence: “If the Son shall make you free, you shall be free indeed.”
Liberty, most Englishmen know, is rightly esteemed one of the highest temporal blessings. Freedom from foreign dominion, a free constitution, free trade, a free press, civil and religious liberty–what a world of meaning lies beneath these phrases! How many would sacrifice life and fortune to maintain the things which they represent! Yet, after all our boasting, there are many so-called freemen who are nothing better than slaves. There are many who are totally ignorant of the highest, purest form of liberty. The noblest liberty is that which is the property of the true Christian. Those only are perfectly free people whom the Son of God “makes free.” All else will sooner or later be found slaves.
Wherein does the liberty of true Christians consist? Of what is their freedom made up? They are freed from the guilt and consequences of sin by the blood of Christ. Justified, pardoned, forgiven, they can look forward boldly to the day of judgment, and cry “Who shall lay anything to our charge? Who is he that condemns?” They are freed from the power of sin by the grace of Christ’s Spirit. Sin has no longer dominion over them. Renewed, converted, sanctified, they mortify and tread down sin, and are no longer led captive by it. Liberty, like this, is the portion of all true Christians in the day that they flee to Christ by faith, and commit their souls to Him. That day they become free men. Liberty, like this, is their portion forevermore. Death cannot stop it. The grave cannot even hold their bodies for more than a little season. Those whom Christ makes free are free to all eternity.
Let us never rest until we have some personal experience of this freedom ourselves. Without it all other freedom is a worthless privilege. Free speech, free laws, political freedom, commercial freedom, national freedom–all these cannot smooth down a dying pillow, or disarm death of his sting, or fill our consciences with peace. Nothing can do that but the freedom which Christ alone bestows. He gives it freely to all who seek it humbly. Then let us never rest until it is our own.
