Simplicity is not the main problem. In fact most profound insights are incredibly simple. But there are two kinds of simplicity. One is the simplicity of a teenager who says “Jesus loves you.” The other is the simplicity of a 90 year old woman having lived through the great depression, lost her husband, and is witnessing her body deteriorate who says “Jesus loves you.” Both are simple, but one is informed by time, wisdom, experience, suffering, and complexity. This is how something can be both profound and simple.
