Everything you think of as true starts in your mind. Sometimes we think of ourselves as more than we are, but we are called to have humility. Your life is not your own.
Negative thinking can be a downfall for us, too. These thoughts can not only take your inner peace, but they can cause you to stumble. It is necessary to guard your mind daily.
How can you filter out the good with the bad and the positive from the negative? You have to make the choice to mentally choose God.
Putting your trust in Him and keeping your focus on Him will ensure that He always remains bigger than your thoughts and problems. You may be going through some bad stuff you wish would all just go away.
I encourage you to trust God. He has never left you and He won’t start now. When you ask Him to help guard your mind, He will also help to protect your peace.
Continue to offer prayers to Him with faith and a thankful heart. What have you not given to Him in prayer that is robbing your mind and life of the peace only He can give you?
