There are people and circumstances that can have a profound effect on you. If that effect is not positive, release it. Learn from them and the experience. Hold them in prayer. Release them with a clear heart (for it is always a heart issue) and move on with your life.
If the effect is positive, cherish it. Pray for them. What you let into your heart will have a profound impact on your life! Appreciate the good in your life. Be thankful of heart. For whatever is taking place right now in your life, there is always good.
