"By many portions and many modes, of old, God, speaking to the fathers in the prophets, in the last of these days speaks to us in a Son, Whom He appoints enjoyer of the allotment of all, through Whom He also makes the eons..." (Hebrews 1:1)
The Apostle Paul, a Jew from the tribe of Benjamin, was selected to reveal to humanity the purpose of the ages made by the Son of God, Christ Jesus our Lord.
"To me, less than the least of all saints, was granted this grace: to bring the good news of the untraceable riches of Christ to the nations, and to enlighten all as to what is the administration of the secret, which has been concealed from the ages in God, Who creates all, that now may be made known to the sovereignties and the authorities among the celestials, through the church, the multifarious wisdom of God, in accord with the purpose of the ages, which He makes in Christ Jesus, our Lord." (Ephesians 3:11)
