31 Days of Purity: A Renewed Mind

Through the month of March, I am inviting you to 31 Days of Purity—thirty-one days of thinking about and praying for sexual purity. Each day features a short passage of Scripture, a reflection on that passage, and a brief prayer. Here is day twenty-nine:

Do not be conformed to this world, but be transformed by the renewal of your mind, that by testing you may discern what is the will of God, what is good and acceptable and perfect.

(Romans 12:2)

Our bodies follow our minds. This is the consistent witness of Scripture, which always places mind before body. Throughout his life, the Christian is to be renewing his mind by the Word of God, to take it into captivity and bring it into conformity. As he does this, his words and his deeds, and even his thoughts, will necessarily follow.

If there is any area where we let our bodies dictate our thoughts and our actions, it is here in the context of sexual purity, in those times when the body seems to cry out in dissatisfaction. When we wallow in sexual sin, we fill our minds with what is impure, as if Philippians 4 commands us to think about whatever is false, whatever is deplorable, whatever is unfair, whatever is impure, whatever is ugly, whatever is critical, if there is any depravity, if there is anything worthy of rebuke, we think about these things. And, not surprisingly, our bodies follow our minds.

It is so much better to heed and to practice Philippians 4 which commands us to think about what is good and noble and pure. “Finally, brothers, whatever is true, whatever is honorable, whatever is just, whatever is pure, whatever is lovely, whatever is commendable, if there is any excellence, if there is anything worthy of praise, think about these things” (Philippians 4:8). Think about those things, brother, and let God transform your thoughts and your actions.

Father, I pray that you would do your work of mind-renewal within me. I know that my behavior follows my thoughts, so I pray that you would help me to think about those things that are true and beautiful. Whatever is true, whatever is honorable, whatever is just, whatever is pure, whatever is lovely, whatever is commendable, if there is any excellence, if there is anything worthy of praise, I pray that you would help me to think about these things and to love thinking about these things.

What Now? Consider joining our 31 Days of Purity Facebook group. It is optional, but you will find it a good place to go for discussion and encouragement. (Note: that Facebook group is for men only; here is one for Women Supporting Men).
