What is this, another oblique reference to the calvinistic peek-a-boo, now you see it, now you don't Trinity? Are you contending that before the birth of Jesus there existed only a binary God?
Scripture indicates that God the Father predestined our salvation through Jesus Christ the Son, and we have that salvation guaranteed to us through the presence of the Holy Spirit.
Ephesians 1:3-6
Blessed be the God and Father of our Lord Jesus Christ, who has blessed us in Christ with every spiritual blessing in the heavenly places, even as he chose us in him before the foundation of the world, that we should be holy and blameless before him. He destined us in love to be his sons through Jesus Christ, according to the purpose of his will, to the praise of his glorious grace which he freely bestowed on us in the Beloved.
We know the plan of salvation was designed before the foundations of the world were laid.
The Father predestinated the plan and the Son and Spirit agreed to the plan .
