Studentdevos.com has a great devotional on the power of your thoughts. Just like images on your phone, your thoughts can be deleted or shared and good thoughts can lead to success, just like focussing on good photos of yourself will lead to a more positive self-image than if you focus on the bad pictures.
Romans 12:2 says, Do not conform to the pattern of this world, but be transformed by the renewing of your mind. Then you will be able to test and approve what God’s will is - his good, pleasing and perfect will.
So if you have a bad thought, delete it and if you have a good one, share it. You can read the full devotion here.
