In the flesh we struggle to conform. The apostles were never found to be stiff or monotonous, they never tried to conform to man's standard. The factor to look at is that they represented the very nature of God rather than the nature of man. Look at the creation. The Creator made variety while maintaining order.
Man seems to thrive on conformity, which always ends in disorder.
How different the standard of God. God loves variety. Now think of a zoo. Look at the wonder of the variety that God has made. Make a comparison of the work we do for God against the work that HE does.
