Why Does the Trinity Matter? (Part 1)

READ : Galatians 4:1-7

God sent the Spirit of his Son into our hearts. (v. 6, NIV)

Too many Christians, living as functional Unitarians, fail to recognize the Trinity’s relevance to their Christian faith and life. The doctrine of the Trinity is crucial because it reveals what and who God really is – one God in three persons. Who would not want to know and understand, though in an obviously limited way, God’s nature as he truly is?

Furthermore, an understanding of the Trinity illuminates the great truths about God’s historical, redemptive actions (completed in and through the Father, Son, and Holy Spirit). God the Father sent the Son into the world to offer a propitiatory sacrifice on the cross – that is, a sacrifice that both appeases the Father’s just wrath against sin and extends the Father’s love and mercy by allowing repentant sinners to escape divine judgment. God the Son, incarnate in Jesus Christ, was able to provide this atonement because he is both God and man. The God-man conquered death, sin, and hell through his glorious resurrection from the dead. God the Holy Spirit is directly responsible for the repentant sinner’s new birth in Christ through regeneration and the believer’s life journey of sanctification. Without all three divine persons of the Trinity, we have no salvation!


We worship you, Savior God, Father, Son, and Holy Spirit!
