In John John 8:34, Jesus says that sin enslaves. We become slaves not only to the sin itself, but also to the author of sin, the devil. We are either servants of God through obedience or servants of the devil through sin.
The bondage that sin produces to slavery, the freedom that comes through serving God is being a beloved son. No one would doubt that being a son is better than being a slave. Obeying God is better than giving in to sin.
True freedom is found only in serving God. There is a false freedom that Satan has been promoting since the Garden of Eden. He has deceived all of us at one time or another into thinking that God is a tyrant who really doesn't want us to enjoy life and has told us not to do certain things. Because we believe this lie, we disobey God (or sin) in the name of freedom.
The Word of God and personal experience proves that the wages of sin is death (Romans 6:23). Jesus is stripping sin of any glamour with which the devil disguises it. Sin brings bondage. The only true freedom is found in Jesus. Jesus not only dealt with the original sin that contaminated the human race, but He also dealt with individual acts of sin.
Even if an individual could stop all sinning, he could not change his sin nature with which he was born. That's the reason we must be born again.
