"Finally, brothers, whatever is true, whatever is noble, whatever is right, whatever is pure, whatever is lovely, whatever is admirable—if anything is excellent or praiseworthy—think about such things". Philipians 4:8
It is so important that we keep our minds cleansed and pure. I know when I struggle with things its usually because I entertain thoughts in my mind. Whether it be a struggle with boys consuming my life, not gossiping, my bitterness ... to name a few, I know that I have set myself up for distruction! You HAVE to take each thought captive EVERY time it comes into your mind. I can almost always pinpoint where it all went wrong when I sin. I can reply the conversation in my mind of Satan's lies and know that I didn't take it to Jesus. I didn't quote scripture, I didn't call Satan out. I did let him in my mind and I did buy into his propaganda.
We have to turn our eyes and ears from this world when we are tempted! Its been helpful for me to have verses on notecards. I have some in my purse, my bookbag, my car. I keep them up at work where I am really tempted to sin! Just yesterday I had an instance where one of the ladies snapped at me, rudely and loud enough to draw attention to the situation, over a misunderstanding! It took everything in me to take it! I immediately pulled out my notecards and read Luke 6:29 "If someone strikes you on one cheek, turn to him the other also".
As angry as I was, God's word calmed my heart so that I didn't react. Praise the Lord for letting me act in a godly way not a worldly way!
