What shall we say then? Are we to continue in sin so that grace may increase? May it never be! How shall we who died to sin still live in it? Or do you not know that all of us who have been baptized into Christ Jesus have been baptized into His death? Romans 6:1-3
What if you choose to commit the same sin over and over again? What about when you fall in the same area time after time and you continue to plunge headlong into a particular area of sinful behavior?
If this describes you, what I can tell you is you are not living as though you believe Romans 6 is true about you. A person who struggles with a repetitive sin either doesn’t care about that sin, or they don’t believe they are able to stop sinning.
These verses tell you that in Christ you have been freed from the power that sin holds over mankind, and that any sinning the Christian does now is by choice. If you are a Christian, you are no longer obligated to obey your sinful thoughts and desires. If you continue to willfully sin, you must not believe that is true. Your sin meets some perceived need in you, and you worship it.
For example: a woman who has as a sinful habit using curse words when she becomes angry knows that she does not have to curse, yet she does anyway. She knows the theology behind her position in Christ and yet she continues to behave in this way. On some level, using those words meets some perceived need within her. She wrongly believes that no other words can convey her true feelings about a subject, or the depths of her anger. It soothes her desire to be understood as “angry” and it is so important to her to be understood in this way that she willingly sins to prove it. In those moments she is not worshiping God, but she is worshiping herself.
Willingly living as a slave to sin, a bondservant to unrighteousness is to deny what Christ has done for her! Anyone who lives as a slave to sin is owned by it in practice while not being its slave in position because we have been freed!
And remember, if you were a slave when the Lord called you, the Lord has now set you free from the awful power of sin. And if you were free when the Lord called you, you are now a slave of Christ. God purchased you at a high price. Don’t be enslaved by the world. 1 Corinthians 7:22-23
When living in the victorious position means enough to you, you will do it. Until then, you live as though you remain a slave to sin and deny the power He gives you to overcome. It is a decision you are making. The guilt you live with is a consequence of your sin. A part of you most certainly hates your sin (and I'm willing to bet you like the consequences of your sin even less) but curiously enough, you don't hate it enough to jettison it.
Here is the good news: the closer you grow in knowledge, wisdom, love, honor, and desire for the Lord, the less you will continue to love your sin. It has to be about Him and not about you. You have to want to glorify Him more than you want to satisfy you. You have to be willing to run away from your desires and toward His glory to avoid the sin. You have to decide it is more important to you to live your position, and to stop living as a slave to sin.
