"My brethren, count it all joy when ye fall into divers temptations; Knowing this, that the trying of your faith worketh patience.  But let patience have her perfect work, that ye may be perfect and entire, wanting nothing."   James 1:2-4

"For all flesh is as grass, and all the glory of man as the flower of grass.  The grass withereth, and the flower thereof falleth away:  But the Word of the Lord endureth for ever.  And this is the Word which by the Gospel is preached unto you."  1 Peter 1:24,25

"For ever, O Lord, Thy Word is settled in heaven."  Psalm 119:89
