3. Then Peter explains this new Gospel message as the doctrine of
peace, the peace proclamation commanded of God; in other words,
salvation and every good thing. The apostle portrays it as a
comforting message, a Gospel of joy and grace, a message not accusing,
threatening and terrifying with a vision of God's wrath for our sin,
as did Moses with his doctrine of the Law. Peter offers to the
hitherto terrified, God's favor, remission of sins and eternal life.
Similarly, of old did the prophets prophesy of this Gospel, calling it
the message of peace. Peter's language is borrowed from them. For
instance, Zechariah prophesies (ch. 9, 10), "He shall speak peace unto
the nations." And Isaiah (ch. 52, 7), "How beautiful upon the
mountains are the feet of him that bringeth good tidings, that
publisheth peace!" Paul offers the same thought (Eph 2, 17), "And he
came and preached peace to you that were far off, and peace to them
that were nigh." A delightful message is this in which God recalls his
wrath and, as Paul says (2 Cor 5, 18-20), reconciles us unto himself,
having commanded the Gospel to be preached to the world for that very
purpose, and the office of preaching to be called the ministry of
reconciliation; and God admonishes us to be reconciled unto himself,
to be his friends, that we may from him receive grace and every good
thing.
4. Second: Peter declares what the Gospel message records concerning
Christ: what he has wrought and the nature of his office--how he
preached and worked miracles in the service, and for the relief, of
all men; what thanks and reward his own people accorded him, in that
they nailed him to the cross and put him to death; that nevertheless
Christ was not destroyed by the power of the world nor overcome by
death, but even retained his freedom, showing himself after death and
letting his voice be heard; and that he is now exalted Lord and Judge
over all.
