You can choose what you think about! 

Every action we have is rooted in the thought that produced it! Wrong thinking makes a way for negative behavior! If we want to change we need to think like Jesus thinks! We need to take every thought captive under His obedience(2 Cor 10:5).
What is Jesus saying about your challenges, life etc. ….? How would He think about those things? Choose to think in the same way because that would determine the way you act and your outcome!
