My son Daniel (he goes by Danny) has his 17th birthday on March 25.  17 denotes victory; a combination of spirit and order, 10 +7.  He is a very good rock climber, nationally ranked actually.  As a teenager you are never quite sure, but he does love the Lord.  I plan to have Psalm 61:2 ("Lead me to the Rock that is higher than I") engraved on a stone and present it to him on his birthday.
 
One other thing I find quite interesting is that he works at a rock climbing gym in Flagstaff, AZ called VERTICAL RELIEF.
 
Wouldn't the Rapture on that day give a new meaning to VERTICAL RELIEF!
