Security and Wonder are two things human souls deeply crave.  
Security is the sense that I am okay, safe where I am.   We deeply desire a feeling of security.  Indeed, if we feel insecure or threatened for too long a period of time, deep psychological difficulties and anguish generally set in.   If you have ever been very short of money and not known where any more might come from - this is an anxious place.  Obvious perhaps, but that would reenforce the point I'm making - that we all are wired with a need for security.  
Wonder is also a need for our souls - we crave, even need, to know that there is more.  More beauty, more transcendence, more glory, more emotional or intellectual joy.  From a child's imagination, to the Hubble telescope - wonder captivates human beings.  
To find both security and wonder, we need something much larger, much bigger than we are.   God again, is the only source of both - God, rightly understood as much bigger, much more glorious that we are.  He is "the almighty God" who can give our souls security.   He is also the God who's majestic - giving our souls the breadth and transcendence that we require to live as healthy people of hope.   
Security and wonder - the life blood of our souls.   Secure where we are; yet full of wonder at the possible.  God, the source of both.
