Now he that planteth and he that watereth are one: and every man shall receive his own reward according to his own labour.
One - one in standing before God; able to do nothing without God. It is only their relative faithfulness with their gifts which will place them higher or lower (Matthew 25:14-30); therefore they ought not to be made by you the occasion, of party divisions.
And every man - rather, 'but ( de (G1161)) every man.' Though in service they are essentially "one," yet every minister is separately responsible, and "shall receive his own (emphatically repeated) reward, according to his own labour." The reward is something over and above personal salvation (1 Corinthians 3:14-15; 2 John 1:8). He shall be rewarded according to, not the amount of work done, but "according to his own labour." It shall be said to him, "Well done, thou good and (not successful, but) faithful servant, enter thou," etc.
