I realize that a person can become so obsessed with heaven that he / she is of no earthly good. But that doesn't seem to be a problem with anyone I know. I do know that in my own life, when I keep a healthy eye on heaven -- I live with more peace now.
"One thing I ask of the Lord, this is what I seek: That I may dwell in the house of the Lord all the days of my life, TO GAZE UPON THE BEAUTY OF THE LORD and to seek him in his temple." (Psalm 27: 4)
