My terms being that whomever I'm discussing something with
must be substantively on topic and clearly responsive,
using as little "cut and paste" from other sources as is reasonable.
Jesus, just as in the case of
the Elect Angels,
where "
the Elect Angels are not Chosen to Salvation as men are,
as that signifies a Deliverance from sin and misery:
seeing
the Elect Angels never sinned,
and so were never in a miserable condition,
and needed no Savior and Redeemer;
"yet
the Elect Angels are Chosen to Happiness,
to Communion with God now, Whose Face they ever behold;
and to a Confirmed State of Holiness and Impeccability,
and to the enjoyment of God,
and the society of Elect men to all Eternity.
"...it may be proper...
to take some notice of
the Election of Christ,
as man and Mediator;
Who is God's First and Chief Elect;
and is, by way of Eminency, called His Elect;
"Behold, My Servant, Whom I uphold, Mine Elect,
in Whom My Soul delights",
(Isaiah 42:1)
"and Jesus is oftentimes called the Chosen of God
(Psalm 89:3; Luke 23:35; 1 Peter 2:4).
"Which Character not only denotes Jesus' Choiceness and Excellency,
and the High Esteem He is in with God; Who, though disallowed,
disesteemed, and rejected by men,
is Chosen of God, and Precious;
If I understand your question correctly,
the transaction was planned for (not predestined) prior to creation
but the transaction itself happened at Calvary.
"2a. With respect to
the Choice of the Human Nature of Christ
to the Grace of Union with Him as the Son of God.
"God prepared a body, or an Human Nature for Jesus,
in God's Eternal Purposes and Decrees;
"in the Book of which all the Members thereof were written,
which in Continuance were Fashioned, when, as yet,
before there were none of them
(Hebrews 10:5; Psalm 139:16).
"Among all the individuals of Human Nature,
which rose up in the Divine Mind, to be brought into being by Him,
this 'body' of Jesus' was singled out from among them,
and Appointed to Union with the Second Person in the Godhead;
"this 'body' of Jesus' was Sanctified, and Set Apart, and Sent into the world;
in which Joseph was a type of it, who was separated from his brethren:
and hence this Human Nature of Christ was Anointed
with the Holy Spirit above His fellows, and Hail the Gifts
and Graces of the Spirit without Measure;
"and was raised to such Honor and Dignity,
as none of the Angels ever were, or will be
(Hebrews 1:13).
"2b. The Character of Elect, as given to Christ,
respects the Choice of Him to His Office as Mediator,
in which He was Set Up, and with which He was Invested,
and Jesus had the Glory of it before the World began.
Jesus Christ was First Chosen (= Elected) and Set Up as an Head;
and then His people were Chosen (= Elected), as members of Him;
Jesus was Chosen (= Elected) to be
the Savior of the Chosen Elect of God;
as
they are Appointed (= Elected) to Salvation by Him,
Jesus is Appointed (= Elected) to be the Savior of them;
"this is meant by laying help on One that is Mighty;
and as their Salvation is through His Sufferings and Death,
Jesus was Foreordained (= Elected), before the Foundation of the World,
to be the slain Lamb; through Whose Precious Blood
their Redemption would be Obtained;
Jesus was Set Forth (= Elected), in the Eternal Decree
and Purpose of God, to be the Atoning Sacrifice for sin,
to make Atonement and Satisfaction for the sins of the Elect,
and Procure the Pardon of the sins of the Elect
(1 Peter 1:18-20; Romans 3:25).
"Christ is Appointed (= Elected) to be the Judge of quick and dead;
as well as a Day is Appointed in which God
Will Judge the World in Righteousness, by the man Christ Jesus,
Whom God has Ordained (= Elected) for that Purpose,
(Acts 10:42, 17:31).
Why leave it out, in a thread concerning The Two Natures of Jesus,
just because someone might be ignorant of it?
