From the time what came to be? - Isaiah 48:16
Isaiah 48: 14-17 (NRSV)
14 "Assemble, all of you, and hear! Who among them has declared these
things? The Lord loves him; he shall perform his purpose on Babylon,
and his arm shall be against the Chaldeans. 15 I, even I, have spoken
and called him, I have brought him, and he will prosper in his way.
God in an inviting tone thru his prophet (Inspired by God's spirit )continues:
16 "Draw near to me, hear this! From the beginning I have not spoken in secret, from the time it came to be I have been there. And now
the Lord God has sent me and his spirit. 17 Thus says the Lord, your
Redeemer, the Holy One of Israel: I am the Lord your God, who
teaches you for your own good, who leads you in the way you should
go."
"Who among them has declared these things", - the worthless idols cannot foretell any of these things, only God can foretell evens to happen accurately ."The Lord loves him"- Who was it ?-Cyrus the anointed one of God was chosen to conqueror Babylon and to liberate his people . (Isaiah 44:28, 45:1)
"Draw near to me, hear this! From the beginning I have not spoken in secret."- God has always by means of his prophets , spoken openly to his people and not in secrets.
"From the time it came to be I have been there."- Nothing is new to God or unforeseen by him, for example , by means of Isaiah, God foretold (it),about 150 years in advance that Cyrus would conquer Babylon. As their Redeemer, God reassures the Israelites, that he is going to liberate them from Babylon.
God is not afraid to prophesy in advance. He is not foretelling it secretly, so that nobody will later be able to say that he did not foretold it . He knows what he will do and foretells it in advance, so that his people at that time and also we down in this time may be assured that he is the true God ,unlike idols that cannot foretell the future.
The Persian ruler "Cyrus the Great" was the one appointed by God, to overthrow Babylon and to liberate the Israelites from their bondage there. The prophesy was made over 150 years earlier, even before Cyrus was born and rise to power, God declared that Cyrus would act as His shepherd: “He is my shepherd,and he shall carry out all my purpose”; and who says of Jerusalem, “It shall be rebuilt,” and of the temple, “Your foundation shall be laid.”(Isaiah 44:28 NRSV)
