The only times "equality" comes up in Scripture in the leading of the Spirit, are the places where God has said that we are not made equal. We are not "cookie cutter" people and we are not "cookie cutter" Christians.
This despite man's unceasing desire for equality.
God gives us justice, man wants equality or better still "the same break as the next guy."
Equality?
I think SCRIPTURE IS YET AGAIN
BOTH-AND.
Equality before The Cross. Certainly. Whosoever will may come etc.
But one sits on the right hand and one on the left and others elsewhere.
Some have greater treasures stored up in Heaven than others.
As my uncle Assembly of God pastor said about his son, my double cousin: Ronnie will probably make Heaven. But he won't have much to spend when he gets there.
Cloned critters, cloned cookie-cutter "Christians," robots . . . probably won't get tickets to Heaven--mostly because such don't exist in the spiritual existential sense I'm thinking of.
