Summary: We worship One God, Who is manifest in three distinct Persons.
“To God’s elect, strangers in the world, scattered throughout Pontus, Galatia, Cappadocia, Asia and Bithynia, who have been chosen according to the foreknowledge of God the Father, through the sanctifying work of the Spirit, for obedience to Jesus Christ and sprinkling by His blood.”
The basis for our salvation is identified in this one sentence, the most condensed outline of the process of salvation in Scripture. Peter also reveals here the complex, multi-faceted nature of God.
Peter writes to scattered followers of Christ, believers who’ve been dispersed due to persecution under the Roman Emperor Nero. He writes to encourage the afflicted. Peter begins by announcing that all three Persons of the Godhead are responding to their suffering. Father, Son, and Spirit are involved in the reasons behind their hardship, and stand ready to provide relief and an everlasting inheritance.
Even today believers face misunderstanding, ridicule and harassment by unbelieving friends, employers, teachers, and family members. In some countries, converting to Christ is punishable by death. Peter shows us the attitude we should have when facing affliction. When people oppose us, we are reminded that we belong to the Triune God and not to this world. Our hope is found in our thrice-holy God. We may be reviled and looked down upon in the eyes of secular society, but our true status is that we’ve been chosen as God’s elect. God has initiated our calling, which means our real home, our true citizenship is in heaven. This makes us strangers in a hostile, foreign land.
According to Peter, all three members of the Trinity work to bring us new life and provide us assurance of our salvation. All Three are involved in our daily lives. Yet we do not worship three Gods. We are not polytheists. The Trinity is a complicated yet essential Christian teaching.
“Trinity” defined-- The doctrine of the Trinity is as follows: We worship One God, Who is manifest in three distinct Persons. In the Tri-unity of the Godhead there are Three-in-One, of the same substance: God the Father, God the Son, and God the Holy Spirit. They are equally God in their being, power, holiness and eternality. God is one in essence and three in Person. Scripture affirms both the oneness of God and the deity of the Father, Son and Spirit. The Father is our Creator, the Son our Redeemer, and the Spirit our Sanctifier. The word “Trinity” comes from the Latin word "Tri-unitos", which means "three in the unity of one." They are distinct, yet not solitary. And while the word Trinity is not found in the Bible, it is a Biblical concept: One-in-Three; Three-in-One.
The Trinity is somewhat of a mystery—this teaching is difficult to grasp, because it is so unique. Theologians have tried to explain the nature of God, but God is beyond human comprehension. We understand part of Who God is, but not the whole.
He is Father>> Our loving Father chose us before we chose Him (Eph 1:4). From eternity past, the Father planned our salvation, so there is no room to doubt our future in heaven. Nothing that happens can change the Father’s sovereign promises to us. We are His elect, chosen people, adopted into His family.
