Is this for real? Maybe, but more likely it is a manipulated picture. Personally, I hope it is the real McCoy because it would be nice to think of God writing a love letter in the sky. Real picture or no, this represents the love of God and the only thing better is action. Which of course, leads me to this passage in the book of Romans....
Romans, Chapter 5
6 For while we were yet weak, at the right time Christ died for the ungodly. 7 For one will hardly die for a righteous man. Yet perhaps for a righteous person someone would even dare to die. 8 But God commends his own love toward us, in that while we were yet sinners, Christ died for us.
Talk is cheap, actions speak louder than any words!!! Christ showed his love for us (even the worst among us) by his sacrifice on the cross!!! Nuff said!!!
