The prophet Isaiah proclaimed that the nation of Israel was chosen by God to be a witness.
“You are my witnesses says the Lord,
and my servant whom I have chosen,
in order that you may know and believe in me,
and understand that I am He.
Before me there was no God formed
and there will be none after Me.”
So we have a cosmic law court with you as witness, and God as the judge as the nations which stand trial for their placing other than YGod as their source ie idolatry.
God’s love was an electing love that chose one nation to be His means of blessing mankind through them. Sadly many do not view them this way.
God chose a people for service to help the rest of mankind through them. Israel’s’ people were not chosen for their sake.
Though Israel may appear to not yet succeeded in its plan to cooperate with redemption, they remain chosen. The identity of the chosen people becomes more clear when we unravel what “Israel” means. It simply means the children of YGod.
Israel still has a role of witness to play in the near future.
Romans 11.12-13 says:
‘Now if their transgressions be then their riches for the world and their failure be riches for the Gentiles, and how much more will their fulfillment be.”
“For of their rejection be the reconciliation of the world, what will their acceptance but from the dead.”
Israel means people of God. They keep the true biblical laws of God. These law keepers will be the witnesses and then it is up to us to find the reality of those ones of Oneness if we want to find the true witnesses.
