The best thing about living a Christ-centered life, however, is how it makes you feel—inside. It’s hard to have a negative attitude about things if and when your life is focused on the Prince of Peace. There will still be problems. Everyone has them. But faith in the Lord Jesus Christ is a power to be reckoned with in the universe and in individual lives. It can be a causative force through which miracles are wrought. It can also be a source of inner strength through which we find self-esteem, peace of mind, contentment, and the courage to cope. I have seen marriages saved, families strengthened, tragedies overcome, careers energized, and the will to go on living rekindled as people humble themselves before the Lord and accept His will in their lives. Heartache, tragedy, and trauma of all kinds can be focused and managed when the principles of the gospel of Jesus Christ are understood and applied.
