If you have an apple and I have an apple and we exchange apples, then you and I will still each have one apple. But if you have an idea and I have an idea, and we exchange these ideas, then each of us will have two ideas.
Sometimes our daily interactions with others are mostly superficial and our personal exchanges simulate commodity trades. Slow down, look around, try to truly engage others in a meaningful dialogue that will allow both of you to grow and benefit.
But the LORD said to Samuel, Do not consider his appearance or his height, for I have rejected him. The LORD does not look at the things man looks at. Man looks at the outward appearance, but the LORD looks at the heart.
