Whatever controls your thoughts controls you. Life can convince you what to think. Don't let negative situations win the battle for your mind. Constant disappointments, relationship and money struggles over time can make you feel inadequate and cause you to question everything you thought you knew. Thats STINKING THINKING and you can't just relax and let your mind take you there! Let God's word be your mind's leash. The truth is, circumstances can NEVER determine who you are.. only God's word can do that. Fortify your mind with the word of God. The man who thinks he can and the man who thinks he cannot are both correct.
