Have you ever eaten something that tasted so good that you ate it too quickly?  I have.  As soon as it was gone, I wanted more.  The taste was beyond description, very satisfying and inviting.  That is the way Jesus is.  The more you fellowship with Him and experience Him, the more you want to fellowship with Him.  He is the one who satisfys us with good things and causes our youth to be renewed like the eagles. 
You have not had this experience yet?  You have not experienced an overwhelming, indescribable experience with Him yet?  Wow!  Yeah, you are missing something.  But don't be disheartened.  You can experience Him.  The scripture says that anyone who comes to Him He will in no way cast out.  It states that for everyone who comes to Him He will give them the ability to become Sons (or daughters) of God.  The scripture promises that if you draw close to God, God will draw close to you.  So take courage.  Take a deep breathe and dive in.  Dive in by saying, "Jesus come into my life, be my Saviour.  I want you and I need you."  You are free to use your own words to express you desire to receive Jesus as your Lord and Savior.  When you do He will immediately come to you.  The scripture says He will take out that old heart and put in a new heart.  You will become a new creation.  A creation that never existed before.  You will become a child of God.  Thats the miracle of new birth.  I'm excited just telling you about it.  When you do, comment and let me know.  If you don't comment, but do receive Jesus as your Savior, welcome to the family.
