Hebrews 13:14  For here have we no continuing city, but we seek one to come.
Luke 12:35-37  Let your loins be girded about, and your lights burning;  And ye yourselves like unto men that wait for their lord, when he will return from the wedding; that when he cometh and knocketh, they may open unto him immediately.  Blessed are those servants, whom the lord when he cometh shall find watching: verily I say unto you, that he shall gird himself, and make them to sit down to meat, and will come forth and serve them.

Philippians 3:13-15  Brethren, I count not myself to have apprehended: but this one thing I do, forgetting those things which are behind, and reaching forth unto those things which are before,
I press toward the mark for the prize of the high calling of God in Christ Jesus.  Let us therefore, as many as be perfect, be thus minded: and if in any thing ye be otherwise minded, God shall reveal even this unto you.
