covet the best gifts

1 Corinthians 12

28  And God hath set some in the church, first apostles, secondarily prophets, thirdly teachers, (Eph. 4.11) after that miracles, then gifts of healings, helps, governments, diversities of tongues.

29  Are all apostles?  are all prophets?  are all teachers?   are all workers of miracles?

30  have all the gifts of healing?  do all speak with tongues?  do all interpret?

31  But covet earnestly the best gifts.  And yet show I unto you a more excellent way.
