There are diversities of gifts, but the same Spirit. There are differences of ministries, but the same Lord. And there are diversities of activities, but it is the same God who works all in all. 1 Corinthians 12:4-6

The work has been bound about, false moves have been made, and Satan has been pleased. If self had not been so carefully, tenderly cherished, lest it should not find room enough to preserve its native dignity, the Lord could have used these differently constituted characters to do a good work and much larger; for in their diversity of talent, yet unity in Christ, was the power of their usefulness. If, like the diverse branches of the vine, they were centred in the vine stock, all would bear the rich cluster of precious fruit. There would be perfect harmony in their diversity, for they are partakers of the nourishment and fitness of the vine.  {Evangelism 101.2}
