Thank you so much Alamo-Girl, for pinging me to your interesting comments, Scripturally based and filled with Wisdom from Above, and to this discussion.
I believe the first disciples themselves are a grand and accurate picture and a proof of your assertion. See how different in personality Peter is from John, yet Christ chose both and used each to great effect - they are still speaking. Look at Stephen compared to James, or Paul in relation to Lydia, Matthew to Thomas.
O! The Creator God is a God of variety as well as of unity. The greatest composition among human creatures whether in music or word or paints must have a multiplicity of notes or words or colors, yet all together used toward the one message of a song or story or painting are seen as one whole.
"The whole is greater than the sum of its parts," mused Aristotle. Indeed, we can look at or perceive each part separately, and do - the wind section distinct from the brass, the yellow in contrast to the red, the one glowing phrase that may stand out from a piece of writing - "It was the best of times, it was the worst of times," for example. Yet who is more content with the painting White on White - should this very post be composed of only one letter? - than with gazing upon any composition by Monet, or to have harmony without the melody? Who, in admiring a poem or song would, after the first reading, go back to a single line or single glowing word, and not always think of it in the beauty of its setting? It is in the context of the whole that the parts are made lovely. The line above from Dickens is often quoted, yet is most sublime to the one who knows the story that follows it.
The talent of a Fred Astaire is in the many taps together and every move - one tap or dance step by itself is only lovely because we know what happens when all are put together by the master!
So it is and so it remains. The Lord of All Himself is Elohim - Father, Son and Holy Spirit, and we are made in His image. It is no wonder then that we who are His creatures, and all that we create as men, follows this divine order!
When God said, "It is not good for the man to be alone," He added not another Adam, but his Eve. Amen.
