At Blue Letter Bible, an Outline Study, The Biblical Basis of the Doctrine of the Trinity by Robert M. Bowman, Jr.
Some excerpts below, but got to the Study for links to the Bible references and sections:
10. What Difference Does the Doctrine of the Trinity Make?
>>> Sovereignty: Because the three persons have each other, we can be assured that God created us only to share the love they have and not as a means to His own end: Act 17:25; Jhn 17:21-26.
>>> Mystery: The triune God is totally unlike anything in our world, and therefore greater than anything we can comprehend: Rom 11:33-36; Isa 40:18.
>>> Salvation: God alone planned our salvation, came to save us, and dwells in us to complete our salvation: 1Pe 1:2; Eph 1:3-18; etc.
>>> Prayer: We pray to the Father through the Son, and also pray to the Son directly, in the >>> Spirit: Jhn 14:13-14; Eph 2:18; etc.
Worship: We worship Father and Son in the Spirit: Jhn 4:23-24; Phl 3:3; Hbr 1:8; etc.
>>> Love: The love among the three persons is the basis and model for our love for one another: Jhn 17:26.
>>> Unity: The unity of the three persons is the basis and model for the unity of the church: Jhn 17:21-23.
>>> Humility: As the persons of the Trinity seek the glory of each other, so we should seek the interests of others above our own: Phl 2:5-11; Jhn 16:13-14.
>>> Sonship: We are "sons of God" as we are united with the Son of God by the work of the Holy Spirit and the adoption of the Father: Jhn 1:12-23; Rom 8:14-17.
>>> Truth: All those who wish to worship and love God must seek to know Him as He is in truth, for God, as Father, Son, and Holy Spirit, is truth: Jhn 4:24; 14:6, 17; 15:26; 16:13.
