The Trinity in Salvation

God is One and God is Three... the Trinity. God in Three Person's - Father, Son, and Spirit. This characteristic of God is a mystery for sure, but He does want it to be totally misunderstood. We have many passages of Scripture where we see the work of God in the triune (three-in-one unity). The Apostle Paul was blown away by this, as we should be. God has revealed Himself and expressed Himself in the Trinity. In Ephesians chapter 1, as Paul is writing from a Roman prison cell to the church at Ephesus and then is to be circulated through the churches, about the Trinity in salvation... 

Ephesians 1:1-14

"Paul, an apostle of Christ Jesus by the will of God, To the saints who are in Ephesus, and are faithful  in Christ Jesus: Grace to you and peace from God our Father and the Lord Jesus Christ.

 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. In love he predestined us for adoption as sons through Jesus Christ, according to the purpose of his will, to the praise of his glorious grace, with which he has blessed us in the Beloved. In him we have redemption through his blood, the forgiveness of our trespasses, according to the riches of his grace, which he lavished upon us, in all wisdom and insight making known  to us the mystery of his will, according to his purpose, which he set forth in Christ  as a plan for the fullness of time, to unite all things in him, things in heaven and things on earth. In him we have obtained an inheritance, having been predestined according to the purpose of him who works all things according to the counsel of his will,  so that we who were the first to hope in Christ might be to the praise of his glory.  In him you also, when you heard the word of truth, the gospel of your salvation, and believed in him, were sealed with the promised Holy Spirit, who is the guarantee  of our inheritance until we acquire possession of it, to the praise of his glory." 

In this passage we see that :

1) God the Father  - ADOPTED (chose) US (vv. 1-6) 

2) God the Son - REDEEMED (purchased.. bought back) US (vv. 7-12) 

3) God the Spirit - SEALED (promised to preserve) US (vv. 13-14) 

And ALL God's children said; "AMEN!!!"
