Practical atheism thrives on deficient views of God, eroding the joy that Christians should experience in their everyday lives, enveloping the disciple in a mist of uncertainty, confusion, and anxiety. The habits of Christianity (its diverse rituals and liturgies) can form disciplines of holiness–but only insofar as they drive from and toward a clear view of who God has revealed himself to be in the Bible. For this reason, the most edifying traditions and authors1 have woven into their theology a robust Trinitarianism, the core revelation of God’s identity to humanity. The doctrine of the Trinity is not the crazy uncle of theology–something Christians only mention when it comes up and only then with hesitation that belies a reticent confusion bordering on embarrassment. Instead the doctrine of the Trinity is crucial not only for an accurate and singular understanding of salvation2 but also for the everyday comfort of Christians beset by the usual but bewildering circumstances that mark their pilgrimage home to their final destination with God.
For the sake of time3 let’s consider the simple Trinitarian statement found in 2 Corinthians 13:14, ”The grace of the Lord Jesus Christ and the love of God and the fellowship of the Holy Spirit be with you all.”
I will assume that if you had to choose a member of the Trinity to be fully God that you would likely choose the Father over the Son and Holy Spirit . Even though we won’t dwell long on the full deity of the Father, there is a wealth of heart-stirring meditation to be done simply around the theme of God Almighty as our perfect, loving Father. Indeed, the doctrine of adoption is both under-taught or mistaught throughout Evangelicalism. But turning from this we are still left in 2 Corinthians 13:14 with the grace of Jesus and the fellowship of the Holy Spirit.4 Let’s consider now how the union of the doctrine of the Trinity with these two Persons and activities of grace and fellowship fuel the joy of the Christian.
