For this cause I also, when I couldn't stand it any longer, sent that I might know your faith, for fear that by any means the tempter had tempted you, and our labor would have been in vain.
For what thanks can we render to God again for you, for all of the joy wherewith we joy for your sakes before our God; Night and day praying exceedingly that we might see your face, and might perfect that which is lacking your faith? ( 1 Thessalonians 3:9-10 )
