A slave is one who is at the disposal of his master. He has no right to choose his path in life or, in fact, even his daily routine. The master makes those choices since he owns the slave. Verse 35 reveals how spiritually serious this is in relation to God, sin, and everlasting life since the slave does not abide in the house forever. "The house" implies God's house. From a statement like this, John later infers that no murderer has eternal life abiding in him (I John 3:15). This is very serious business.

The Elements of Motivation (Part Seven): Fear of Judgment
The basic concept of sin is failure—failure to live up to a standard, failure to hit the bull's eye, failure to stay on the path. The slavery Jesus speaks of is bondage to a pattern of thinking that produces failure. This is what God wants to deliver and convert us from. All who come out of the world have been addicted, held in bondage, to ways of thinking that produce failure, mental illness, physical disease, and death. God desires to give us freedom through applying truth in faith and love for the Father, His Son, and the brethren.
He has revealed Himself, His way, and His truth. Do we believe it? Will we discipline ourselves to use the truth? This is the responsibility that faces us. It has been done, and we can do it. Will you?

Eating: How Good It Is! (Part Five)
Instead of freedom, habitual sin brings about an enslaved consciousness, and one can gain insight into its nature by comparing it to chemical addiction. Like the chronic use of drugs, habitual sin causes a hardening of the heart (Job 9:4). Just as a junkie needs more of the addictive drug more often, habitual sin lowers the barriers of our conscience to more sin. As Jesus Christ says, “Sin no more, lest a worse thing come upon you” (John 5:14).
Our religion—our connection to God—provides us with the moral compass necessary to define both sin and the standards we need to walk worthy of our calling. This same connection also provides us with the ultimate solution for our addiction to sin—His love.
We do not live or commit sin in a vacuum. Each sin lowers our inhibition to further transgression and often causes collateral damage to those close to us and beyond. More importantly, it separates us from our Father and His love, without which we would be eternally lost. We can be assured, though, that because of our heavenly Father's powerful love for each of us, He has provided the perfect antidote to all of our sinful habits in the life and the blood of Jesus Christ.
