Slavery in ancient times, whether voluntary or involuntary, was rigid, and gave the master over the slave, an absolute right in all matters concerning that slave.
In the reality of creation, there are only two possible masters.
The first, is sin, and second is God. There is no third choice, and no one can be a master over themselves.
God represents truth, and sin represents all that is false.
If you dedicate yourself and pursue truth, then you are a servant of God. But that means you have to obey God, which means you have to obey all of His mandates. And saying it does not make it so. Your thoughts and actions testify as to the reality of your obedience, or lack of it.
If you do not dedicate yourself to truth, then by default you are a servant of sin. Sin represents all that is not truth.
You cannot serve two masters. Sin will take you as a slave no matter what you say or think or do. However God, will not accept you as a servant, unless you are completely obedient.
Slavery in the ancient world, gave the slave no rights, and expected absolute obedience to the master.
Therefore, there is no compromise, there is no, a little of this or a little of that. Slavery or service is an all or nothing arrangement. And in the arrangement you have no say as to the rules of the arrangement.
Disregard or indifference toward God, or trying to define your own rules, and certainly disobedience by ignoring the mandates which are clearly stated in the Bible, automatically place you under the service of sin.
We are all sinners of course, and we all fail from time to time. But the pattern of decisions that you make in your day-to-day life, determines your course in life.
The spiritually advancing believer, will fail from time to time. However, the pattern of obedience, determines the believers path, despite an occasional stumble.
The believer who is inconsistent within their spiritual life, who pretends or plays games with appearances for the sake of others to see, is in reality obedient to sin, and going nowhere in the spiritual life.
Sin leads to death. And death is a separation from something. And in this case the pattern of sin becomes a separation from ones spiritual life, and the completion of oneself. So, the disregard of the spiritual life, means you’re going nowhere, and you will end up with nothing. Which is just about what happens in death.
Righteousness, on the other hand, is the concept of pursuing ones spiritual life, by means of obedience to Gods mandates, which stated in the simplest form, means consistent confession for the purpose of fellowship, consistent daily Bible study for the purpose of learning, and consistent application of Bible doctrine for the purpose of enhancing ones spiritual growth.
In sin, you do nothing and you gain nothing.
In righteousness, you study, listen, and learn daily, and you grow and you can gain everything.
