Every single human being is unique. We see so many faces that sometimes we take for granted the breathtaking diversity that an infinite God displays throughout the ages by creating completely unique individuals who each have a chance to inhabit His Kingdom.
He seals up the hand of every person, that all men whom he made may know it.
Why would an infinite God endow each creature with a completely unique set of characteristics, personality traits, physical attributes, and carry that unique signature down to the cellular level of their uniquely scripted DNA? Simply because He desires a unique relationship with each one of us.
