He accomplished Reconciliation !
Rom 5:10
10For if, when we were enemies,
we were reconciled to God by the death of his Son, much more, being reconciled, we shall be saved by his life.
He accomplished Reconciliation , that is, His Death ALONE has reconciled to God ALL for whom He died, that is precisely what the verse tells us. This reconciliation is Two Fold, it is objective, by which all the elect of God, of all time, by Christ's Death ALONE, have been reconciled to God, not that they were made reconcilable, but actually reconciled, a finished transaction, a done deal !
Can a person be reconciled to God by the Death of His Son and be a Unbeliever and at enmity with God by Nature ? Yes, of course. Paul in
Rom 5:10 is stating to Believers, that WHEN or WHILE we were Enemies of God, even THEN, we had been Reconciled to God by the Death of His Son. You see when a sinner who Christ died for , and His Death had satisfied God's Law and Justice on their behalf, those sinners, who are born dead in trespasses and sins
Eph 2:5, who are born as OTHERS , by Nature Children of Wrath
Eph 2:3, Who are born by nature Ungodly in their manner of life
Rom 5:6 , All such differ from from all others who are born in the same condition, these have already objectively been reconciled to God by the Death of His Son, and to all of them is the PROMISE GIVEN, that they shall be SAVED [ Subjective Reconciliation or Conversion which includes being given both Faith and Repentance] BY HIS LIFE !
To deny this subjective reconciliation to any for whom Christ died, is a denial of the Gospel, the Word of Reconciliation; And since it is obvious from other portions of scripture that everyone in the world without exception shall not be saved by His Life, then reason would tell us that the World in
2 Cor 5:19 is limited to only those that actually Saved by His Life
Rom 5:10. So the conclusion is this, If anyone in that world of
2 Cor 5:19 is not saved by Christ's Life as promised in
Rom 5:10b, then the scripture has been proven to be false, and Paul and the other Apostles are found to be False Witnesses ! However, I am absolutely SURE that the Scripture is True and that the Christ I witness of did actually accomplish and effected reconciliation to God for all whom He died, and not one shall be Lost..
