"Sow a thought and you reap an act;
sow an act and you reap a habit;
Sow a habit and you reap a character;
sow a character and you reap a destiny."
Isn't it funny how things always start out so small. As this quote so wisely points out all the trouble (or good things) start in our minds with our thoughts. No one usually forms a bad habit overnight. Usually no one ever gets better overnight either. For instance, I am overweight. That didn't happen overnight, and I can assure you that it is not coming off overnight either. The problem started in my mind where all I wanted to think about is wanting to eat too much or for the wrong reasons. Those thoughts turned into the act of eating when I shouldn't eat. Those acts turned into a habit of eating too much. After eating too much for several years, now I am obese and have diabetes. Now I have the hard task of trying to reverse the damage and change my thinking patterns so that the bad acts and habits can eventually change. That is why the scriptures say:
2 Corinthians 10:5 (NIV)
We demolish arguments and every pretension that sets itself up against the knowledge of God, and we take captive every thought to make it obedient to Christ.
For the word of God is living and active. Sharper than any double-edged sword, it penetrates even to dividing soul and spirit, joints and marrow; it judges the thoughts and attitudes of the heart.
Hebrews 3:1 (NIV)Therefore, holy brothers, who share in the heavenly calling, fix your thoughts on Jesus, the apostle and high priest whom we confess.
I think we like freedom in our thoughts and feel it is harmless to let our thoughts run wild. But here is the breeding ground for every evil. If a negative or sinful thought is allowed to continue, it will breed other negative or sinful thoughts. On the other hand the same is true with pure and good thoughts. That is why we are encouraged to fix our thoughts on Jesus. He'll take care of the rest!
