" It’s easy to get negative and say things such as: “I don’t understand why my child got off course. Why did I come down with this sickness? Why did these people do me wrong?”
Instead, do as Daniel did. Get up every morning in the midst of the battle, look up and say, “Lord, thank You for another great day. I know you are well able, bigger than my problem, greater than this sickness, and more powerful than my enemy. Thank You that today things will change in my favor.”
Especially in difficult times, make sure you put on that fresh new attitude. Set your mind for victory and keep it set. When negative thoughts come, dismiss them and make a declaration like Daniel’s: “My God is well able. He’s done it for me in the past and I know He’ll do it for me again in the future.”
My challenge today is for you to keep your mind going in the right direction. When you’re positive, you are in the jet stream of God. Learn to think thoughts on purpose: “This will be a great day. Something good is going to happen to me.”
Start off your day in faith. If you develop this positive mind-set you’ll not only be happier, healthier, and stronger, but also, I believe and declare, you will accomplish more than you ever imagined. You will overcome obstacles that looked impossible, and you will become everything God has created you to be. You can, you will! "
