False dichotomy nonsense! 2 Cor 5:19 is about the ministry of reconciliation meaning God the Father was in Christ reconciling the world, which (in whole) was before at enmity with God, to himself. It was about taking away that enmity which could not otherwise be removed from the world (in whole) except in the blood of Christ. To try to twist and limit the meaning to be the “world of the elect” and add the false dilemma that it would otherwise have to mean that everyone got saved is otter systematic force-to- fit nonsense and distorts the very meaning of this MINISTRY of Christ which is spoken of.
namely, that God was in Christ reconciling the world to Himself, not counting their trespasses against them, and He has committed to us the word of reconciliation.[2 Corinthians 5:19]
To be reconciled is to become friends again. Now, if that is true, and it is, it can not mean that the world, as in all whoever lived, are being reconciled, but those who believe. Those who die lost can never be considered reconciled to God. Neither can they be considered a friend of God. In James 2:23, James wrote and the Scripture was fulfilled which says, “AND ABRAHAM BELIEVED GOD, AND IT WAS RECKONED TO HIM AS RIGHTEOUSNESS,” and he was called the friend of God. So, God is in Christ reconciling the world, but only those who believe will be reconciled.
