Those who are discouraged need to understand. God has a purpose and God has a plan.
He created light. He created you. We’re just learning now the things light can do. It travels in waves and particle beams. It bathes us in warmth and cosmic streams. With photons it moves the hearts of the stars, and sends itself to Earth and to Mars.
The more we discover how it works, the more questions we find to answer the quirks.
And in the same way, the more we know God, the less we know which doesn’t seem odd. For God is light and God is love, who showers us all from places above.
