What does it mean that the Body of Christ is Christ's compliment or fullness?
Fullness/compliment means the Church, His Body, completes Christ. When Christ finally has the Body in His presence, He considers Himself complete. As Eve was the completion of Adam, so the Body of Christ will be the completion of Christ Himself, composed of both Jews and Gentiles as fellow heirs.
Les explains that the word fullness in Ephesians 1:23 means compliment. The Church is Christ's Body, and as His complement, it is what makes Him complete. When Christ finally has the Body in His presence, He Himself considers Himself complete. Les illustrates this from Genesis: Adam was alone, naming the animals, and none had a mate for him, so God said He would make a helpmeet. The other word for helpmeet is compliment. Therefore, as Eve was the completion of Adam, so also will the Body of Christ be the completion of Christ Himself. In Ephesians 3:6, this same body includes Gentiles as fellow heirs, of the same body, and partakers of His promise in Christ.
Which is his body, the fulness of him that filleth all in all.
