Set your minds on things that are above, not on things that are on earth. (Colossians 3:2)
Meditating on this set me to thinking about a serious battle I had as a child/early teen with taking every thought captive and submitting it to the Lordship of Christ. For several years I had to wage a battle in my mind... minute by minute taking EVERY thought captive. It is uncanny the extent to which the thoughts/attitudes which we willingly or unknowingly allow in our minds shape our attitudes, abilities, and actions.
This truth is vividly illustrated in Genesis 4:2-7
Now Abel was a keeper of sheep, and Cain a worker of the ground. In the course of time Cain brought to the LORD an offering of the fruit of the ground, and Abel also brought of the firstborn of his flock and of their fat portions. And the LORD had regard for Abel and his offering, but for Cain and his offering he had no regard. So Cain was very angry, and his face fell. The LORD said to Cain, "Why are you angry, and why has your face fallen? If you do well, will you not be accepted? And if you do not do well, sin is crouching at the door. Its desire is for you, but you must rule over it."
Just like Cain, I do not do well, I indulge in a fallen face, and suddenly...sin is crouching at my door, desiring to devour me...to eat me alive...to destroy me. But...but says the Creator of my mind, my spirit, my will...you must rule over it.
I really do not have a choice. Like it or not, feel like it or not, want to or not, I must rule over it, dominate it, annihilate it, master it, or it will do so to me. My enemy the devil is like a roaring lion seeking who he may devour, and if he finds me without my armor on he will certainly eat me alive.
Finally, be strong in the Lord and in the strength of his might. Put on the whole armor of God, that you may be able to stand against the schemes of the devil. For we do not wrestle against flesh and blood, but against the rulers, against the authorities, against the cosmic powers over this present darkness, against the spiritual forces of evil in the heavenly places. Therefore take up the whole armor of God, that you may be able to withstand in the evil day, and having done all, to stand firm. Stand therefore, having fastened on the belt of truth, and having put on the breastplate of righteousness, and, as shoes for your feet, having put on the readiness given by the gospel of peace. In all circumstances take up the shield of faith, with which you can extinguish all the flaming darts of the evil one; and take the helmet of salvation, and the sword of the Spirit, which is the word of God, praying at all times in the Spirit, with all prayer and supplication. (Ephesians 6:10-18)
This is my only defence...to put on the whole armor of God and to take every thought captive in submission to the Lordship of Christ.
