How to have real peace of mind and heart? The Bible teaches two kinds of peace. One is given by the world; the other, by Christ Jesus. “My peace I give to you; not as the world gives, do I give to you.” The natural man tends to seek after the real peace of this world. His surest formula to have the tranquility of mind and soul is to have a whirl with friends. Or, sometimes he would choose to waste his energy in mountain climbing or travels to attain real peace hopefully.
