Anyone who’s experienced being enslaved by a life-dominating sin knows how easy it is to let that struggle become the lens through which you see all of life. You know how deadly the sin is. You know the power it possesses, and how powerless you feel to resist it.

Many people wrestling with addiction see their entire moral responsibility resting on a single prohibition: Thou shalt not..

They start to measure the strength of their relationship with God based on whether they looked at pornography that day. It doesn’t matter what else happened, good or bad—refraining from sexual sin becomes the sole gauge of spiritual health.

Living with Blinders

There are two pitfalls with this type of thinking. First, you become uninterested in any other area of sanctification in your life. Lying, stealing, idolatry, and unrighteous anger don’t even register as areas of needed growth because sexual sin has given you tunnel vision to any other problems. Your day may have been filled with selfish and self-indulgent pursuits, but, in your mind, it was a great day because you didn’t look at porn.

The second pitfall is just as soul-damaging. Letting your entire day rest upon your ability to perfectly resist sexual temptation also blinds you to the good work God may be doing in your life in other areas. Sexual sin is usually the fruition of many other, deeper heart issues that God is slowly and surgically redeeming. There may be much groundwork being done in your life even while you continue to lose many battles against temptation. Blindness to this good work that God is doing can co-opt a trajectory of growth through discouragement and despair.

Take off the Blinders

It’s time to take off the blinders. It’s time to embrace the full panorama of God’s redemptive purposes for your life. On the day of judgment, God is not only interested in what sins you refrained from. He’s equally interested in what good fruit your life produced. This is why theologians have developed two categories for sin: sins of commission and sins of omission. Sins of commission are the sins we commit. We lust, we steal, we lie, we covet. We focus most of our repentant energy on sins of commission. And that’s understandable. The Ten Commandments are largely addressing sins we commit. That is why eight out of the ten are stated in the negative: Thou shalt not. . .

But it was paradigm-shifting for me to read the Westminster Larger Catechism and realize that with every prohibitive commandment is an implied command to do its opposite instead. Not taking the Lord’s name in vain implies the command to revere his name in honor. Not killing implies the command to actively preserve and promote life in others. Not lying implies the command to speak the truth in love to build up your neighbor. Failure to do the opposite of these prohibitions is also sin. Sins of omission are the failure to do the good which God commands. Sin is not just what we have done, but also what we have left undone.
