Body Image

As a descendent of Adam and Eve, you are the Creator's crowning achievement; a marvel of precision design and engineering and fashioned "in His image."
God spoke the heavens and the earth into existence, along with the animals on land, birds of the air, and fish of the sea. For humans however, He "formed man out of the dust of the ground, and breathed into his nostrils the breath of life, and man became a living soul." He put some time and effort into us. Of all His creation, we're the only being that are made "in His image," and we're the one's that He died for on the cross.

So don't let people, tv, magazines, etc shape (pun!) the way that you see yourself. The fact is, you're a masterpiece. Need to lose some weight? Go for it! Eat less junk food and more stuff that's healthy for you. Want to tighten it up a little? Have at it! Eat less junk food and more stuff that's healthy for you.
Want to build muscle? Eat less junk food and more stuff that's healthy for you (and lift heavier objects more often).

Eat what God gave us for sustenance and move the way He biomechanically designed you to move...Just don't get all bent around the axle about what you look like... you're awesome.
