Then cometh the end, when he shall have delivered up the kingdom to God, even the Father; when he shall have put down all rule and authority and power.

For he must reign, till he hath put all enemies under his feet.

The last enemy that shall be destroyed is death."-- 1 Corinthians 15:20-26.
[544]"The mystery" is the Christ, the anointed class--Jesus the head and his body members--designated in the Scriptures as the seed of Abraham, according to the promise.

(Colossians 1:26,27) It is the repeatedly announced purpose of Jehovah that through this seed all the families of the earth shall be blessed.

(Galatians 3:8,16,27,29) Jehovah has devoted much time and effort to the development of the seed of promise.
