For as he thinketh in his heart, so is he (Proverbs 23:7).
You have the ability to choose what you should think about and reject what you shouldn’t. This might sound like a mystery to some people because their minds run riot all the time! But the Bible says "whatsoever things are true, whatsoever things are honest, whatsoever things are just, whatsoever things are pure, whatsoever things are lovely, whatsoever things are of good report think on these things” (Philippians 4:8). That implies you can direct your mind to think the right thoughts only! You can control your thoughts.
Thoughts as more than mere imaginations; they are mental pictures of the mind with instructive or destructive capabilities. Thoughts, many times, are your own creation “they are the mental constructions of your mind that are based on your imaginations. They have the power to keep you in bondage, or liberate you to be the best of you. That’s why until you change a man’s way of thinking, his life and the circumstances of his existence will not change. That’s how powerful our thoughts are, and this is the reason we’re admonished in Scripture to choose our thoughts; think only on things that are just, pure, lovely and of good report.
Don’t let your mind wander off with the wrong thoughts; discipline your mind to choose the thoughts you will accept and process. The Bible says to mount a garrison over your heart (Proverbs 4:23); don’t allow just every thought come in. Reject thoughts that tend to demean or depress you; accept the thoughts of success, joy, victory and prosperity that are based on God’s word. Your life goes in the direction of your thinking, for you’re the character of your thoughts.
So, it doesn’t matter what happens to you, or what unpleasant situation you find yourself, you can either decide to remain there or come out of it by imbibing the right thinking! Appraise the situation from the standpoint of God’s Word, for nothing in this life can make you disadvantaged.
