There is design and order to all things. Consider the egg. Eggs are considered one of the healthiest foods on the planet. They contain small amounts of almost every vitamin and mineral needed to fuel the human body.
Eggs usually hatch in multiples of sevens. The potato bug hatches in seven, the canary in 14, the hen in 21, ducks eggs in 28, mallards in 35, parrots in 42, kiwis in 77.
The lower part of the egg yolk is dense and heavy. The upper part of the yolk is light and thin, which causes the yolk in the egg to always float upright no matter how you turn the egg. There is a rope of albumin attached to the side of the yolk and to the side of the egg’s shell to help stabilize the yolk inside. The shell has a large, thinner end and a small, thicker end. There is an air chamber in this larger end of the egg that you will notice whenever you boil and egg.
The baby chick always emerges from the larger end of the egg because the yolk never changes position, and the head of the chick is always in the larger, thinner end of the egg. The bill of the developing chick is too soft to break through the shell, and so a hard substance grows over the bill. As the chick begins to breathe and its body swells, it uses up the air in the pocket. After two days, the chick uses the hard substance on its bill and lunges for more air, breaking out of the shell. But the real mystery of the egg is how that slimy yolk turns into a fluffy living chick in 21 days.
The Apostle Paul wrote to the Romans, “Through everything God has made, they can clearly see his invisible qualities—his eternal power and divine nature. So they have no excuse for not knowing God.” Romans 1:20 (NLT)
