What's in the # 7? Why is it God's perfect #?

What's in the # 7? Why is it God's perfect #? When in fact 7 is an odd #, just think, there are 7 days a week. 7 wonders of the world. In the bible you must forgive a person 70x7. Even the word FORGIVE has 7 letters. There were 7 last words. The rainbow has 7letters. Even the word PROMISE. Maybe God designed it. For even the word MYSTERY has 7 letters. Begin to see all the 7s in life...... and now, use OLAY TOTAL EFFECTS to fight 7 signs of skin aging...hehe...:)
