from a letter by Samuel Rutherford, Aberdeen, March 6, 1637

.....Let not the world be your portion; what have ye to do with dead clay?  Ye are..... but a lawfully begotten child; therefore set your heart on the inheritance.  Go up beforehand, and see your lodging.  Look through all your Father's rooms in heaven:  in your Father's house are many dwelling-places.  Men take a sight of lands ere they buy them.  I know that Christ hath made the bargain already; but be kind to the house ye are going to, and see it often.  Set your heart on things that are above, where Christ is at the right hand of God.
