How was Eve a complement to Adam?
God said it was not good for man to be alone and promised a help mate. Eve was that complement, the counterpart who completed Adam in their relationship. She supplied what was lacking so the man was no longer alone, and together they formed the whole that God designed.
Les teaches that when God said it was not good that man should be alone, He made him a help mate, and the word carries the idea of a complement. Eve was the complement that completed Adam in that relationship. Les connects this to the body of Christ, explaining that as Eve was the complement that completed Adam, so the body of Christ is that complement of which Christ is still waiting for, looking for, and when it is suddenly filled and the last one is brought in, He will take it to Himself. This shows that complement means a completing counterpart, not merely an assistant.
And the LORD God said, It is not good that the man should be alone; I will make him an help meet for him.
