Our lives are grounded in the Holy Trinity. We owe the origins of who we are and who we can become in Jesus Christ, to the one God: Father, Son, and Holy Spirit. The Trinity is a basic of Christian belief. The God revealed in Jesus Christ and made known to us by the Holy Spirit is one God. God is one; but God is three persons. These three are eternal, sharing one “substance” or essence or being. They are three distinct “persons” who are active in the world—and in our lives—as Scripture proclaims. In interpreting Paul’s words: “And because you are children, God has sent the Spirit of his Son into our hearts, crying ‘Abba! Father!’” (Gal. 4:6), Luther recognizes what the church came to believe is the work of the Triune God in bringing us to become children of God. Each of the three persons is involved in our lives of faith. The full Trinity brings salvation to us.
We are made in the image of God the Father who because of Sin sent one who man and God, Jesus. Jesus lived as we once did perfect image of God. Yet Jesus' Perfection went even further. had he only been a sinless man his death would have only paid for the sin of one man, but because he was also God His death was sufficient to pay the price for the sins of the whole world, past present and future. Lastly it is the person of the Holy Spirit who gives us the power to believe all of this through the Word of God. How this occurs is a sublime mystery. The Trinity is not an abstract doctrine to baffle us. It is the reality of our lives, as created by God and as adopted into the family of God as God’s children. Praise the Holy Trinity!
