Titus 3: 3

For we also were sometimes foolish, disobedient, deceived, serving divers lusts and pleasures, living in malice and envy, hateful, and hating one another.

Romans 6:16Know ye not, that to whom ye yield yourselves servants to obey, his servants ye are to whom ye obey; whether of sin unto death or of obedience unto righteousness?
One thing I want our minds to be drawn to is the fact that by our daily actions we choose who is our Lord.
One who is so much engaged in satisfying all sorts of fleshly passions and pleasures might find it difficult to embrace the fact that what we do with our bodies determines who is our lord whether we admit it or not.

We are so much caught up in the delusion that we are free to do whatever we want and have accepted this idea that we are kind of masters over our bodies by the various activities we engage in so that when one is so much into smoking or getting drunk or any form of pleasure, one thinks that they are just satisfying themselves because they have the FREEDOM to do so.
I believe what the opening verses imply is that by our actions in the body we are choosing who will be the master over our lives; sin unto death or obeying God unto righteousness.
We feel that true freedom is when we are permitted to explore and satisfy all forms of pleasure but the very opposite is what Paul is communicating.

The gospel of Christ tells us that it is in surrendering to the Lordship of Christ that we have true liberties. He gives us that which ultimately satisfies us and not to give in to all manner of pleasures which in the end leaves us emptier than before.
Upon meditating on the gospel of Christ for quite some time, I have concluded that the fellowship with God is God's ultimate desire for us and that is why He gave us the Holy Spirit.

Jesus Christ made us understand that the Father would not withhold any good thing from us and the interesting thing is that He talked about the Holy Spirit being the Gift of the Father even when the people He was addressing were talking about material needs. (Luke 11:13)

Like the Samaritan woman at the well, it is not in exploring all sorts of sexual pleasures that satisfy. We become slaves when we always respond to all the natural inclinations of our flesh. We are not truly free if we do so.
However, we will be ultimately satisfied when we continue in fellowship with God as this is what we see taking place in the GENESIS account of creation.

I would want to humbly submit to you that it is in submitting to the Lordship of Jesus Christ and continuously yielding to the Holy Spirit are we truly Free. That is the Liberty in Christ.
