But when the kindness of God our Saviour and His love for mankind appeared, He saved us—not by works of righteousness that we had done, but according to His mercy, through the washing of regeneration and renewal by the Holy Spirit. He poured out this Spirit on us abundantly through Jesus Christ our Saviour, so that having been justified by His grace, we may become heirs with the hope of eternal life.

Titus 3:4-7 (HCSB)

The way we see the Trinity will influence how we practise the Christian life.

The dogma of the Trinity, far from being an abstract theological concept, is surprisingly practical. The gospel and the message of salvation wouldn't make sense unless all three Persons of the Trinity worked in unison.

The Gospel is inherently Trinitarian.

Each Person of The Trinity is equal, but each person serves a distinct function. The Father loves us and gives His Son to us. The Son loves us and gives Himself for us. The Spirit loves us and gives Himself to live in us. We can see that God is very relational—and by incorporating us into the wonderful family of the Trinity, we can enjoy close fellowship and relationship with Him.

It is by belonging to this family of the Trinity that we learn how to live and serve as sons and daughters of God. This amazing privilege of sonship and adoption frees us from religious performance and self-efforts. When you take the posture of a beloved child of God, whatever you do in His name is done with the fullness of the life of the Trinity living in and through you.

If your reason for reading the Bible, serving and praying is to satisfy an obligation as a Christian, you will not enjoy doing them in the long run. You might even suffer from ministry fatigue and unhappiness. This is because you prioritise your routines over your relationship with God. But if you put your relationship with God over what you do for Him, you will discover and experience the powerful workings of God's grace to will and act accordingly.
