If you want to lose weight, change bad habits, or remind yourself that you "can do it" then you may have recited Romans 12:2 at some point.
Do not conform to the pattern of this world, but be transformed by the renewing of your mind. Then you will be able to test and approve what God’s will is—his good, pleasing and perfect will. NIV
It's a good thing to apply this scripture to many situations. We underestimate how renewing our minds can bring about many changes in our lives. Strongholds can be broken and bad habits can be done away with by this one thing. But it's interesting that the same applies for those in their single season as well. Sexual sin, lust, impure thoughts, idolizing marriage, frustration with being single, and so much more can be properly handled by applying this simple truth.
Sexual sin was a struggle of mine. It took 7 years for me to stop fornicating, though God was speaking to me about it all along. When I renewed my mind and decided I could do it, I gave it up just like that. But that was only step 1. I also had to work on masturbation and even pornography at one point. The same concept was applied: renewing my mind. I had to read the Bible, apply the Word, repent, and ask God to assist me as I embarked on my journey to please Him. I asked that, yet at times I would be convicted on an action I was about to partake in, only to proceed and do it anyhow. My mind wasn't renewed. My thoughts were NOT fixed on things that were excellent and praiseworthy.
I believe at one time I was close to idolizing marriage. Many are unsure what this even means. Let's just say that if your daily thoughts include marriage, when it's going to happen, being frustrated with being single, etc, then you may be idolizing marriage. At least borderline. Over time, I had to meditate on Matthew 6:33. "But seek first his kingdom and his righteousness, and all these things will be given to you as well." I renewed my mind to crave God more than I desired a husband. I realized He could love me better and best. I learned that I wasn't ready for marriage in any way possible. I acknowledged that He was still creating something in me, while molding me to be used for a greater purpose. Had I not renewed my thought process and entire way of thinking, this would have never taken place. I would still be stuck in a world of sexual sin.
Know that for me, it was a step by step process. I didn't wake up one morning and say, "I love you God. Bye bye sex, masturbation, pornography, impure thoughts, lustful desires, the persistent desire for a husband, etc." I'm not sure what your focus is right now. I'm not sure what your struggle is. I'm not sure what it is you're desiring or wanting at this moment. But I challenge you to renew your mind and meditate on His Word. I dare you to let His peace and Words invade your heart and mind so that you can be changed, one step at a time.
Do I still struggle with certain thoughts? Absolutely. But I reach out to those who can hold me accountable. I fix my thoughts on things that are pure. I go to God. I listen to worship music. I reflect on His promises. And in those moments, I know I'll be OK. I continue to seek Him first and know that in due time, all these things will be given to me. His good and pleasing will is perfect for me.
