There seems to be an apathetic attitude among Christians when it comes to disciplining the mind. The person who holds either of these assumptions is only fooling himself. Failing to come to grips with this issue leads to an empty, unstable life, and victorious, joyous living will never be real. First, let me state one obvious fact God can read our minds. The Lord knows the thoughts of man.
Nothing is done in secret.
There is Someone who always sees. That's a sobering thought and should convince us that what we think about can be either a source of joy to God, or a source of grief. We focus most of our thoughts toward either the past or the future. A worrying person constantly thinks about the possibility of future harm or failure. If we entertain pictures in our mind of past hurts, our emotions begin to relive those experiences.
