In the worldly sense, freedom implies that one is devoid of any subjugating force, but the Bible teaches us that true freedom indeed comes from subjugation; subjugation not in the sense of slavery, but in the sense of surrendering – total surrender. The created world is already in a state of slavery, in bondage to sin, because of the willful fall of man (Adam) by which sin and death entered the world (Romans 5:12). All of creation groans and travails in pain to be liberated and we groan to be adopted by God (Romans 8:23), no longer subject to sin (Genesis 4:7), but to the Savior Jesus Christ.

Points to ponder:
True freedom comes from being subject to Jesus Christ, who is Lord and Master (John 13:14). Are you/I subject to sin or the Savior? In other words, are you/I still under the slavery of sin or have we totally surrendered our lives to Jesus Christ, the Savior? The answer to this question would determine if you/I are truly free or not. True freedom comes by subjugation (total surrender) to Jesus Christ, for he/she whom the Son of God makes free, is free indeed (John 8:36).

Romans 8:21-23 (KJV)
21 Because the creature itself also shall be delivered from the bondage of corruption into the glorious liberty of the children of God.
22 For we know that the whole creation groaneth and travaileth in pain together until now.
23 And not only they, but ourselves also, which have the firstfruits of the Spirit, even we ourselves groan within ourselves, waiting for the adoption, to wit, the redemption of our body. 

Galatians 5:1
1 Stand fast therefore in the liberty wherewith Christ hath made us free, and be not entangled again with the yoke of bondage.
