“If you love me, you will keep my commandments.” Jesus asks us to obey Him out of love—not out of duty, honor, or self-interest. Our motivation for the Christian life is to be nothing less than the honest love of the person of God.
Jesus promises us another Advocate, in Greek Parakleton, from which we get our Latinized word Paraclete. This word translates poorly into English, but can be rendered as legal counselor or comforter. The “Spirit of truth” is on our side against the accusations and temptations of the world, the flesh, and the Devil. The presence and advocacy of the Spirit is not a condition of our fidelity, but a gift freely given by Jesus for our consolation and strength. Jesus knows that we can do little to defend ourselves on our own merits; we need Divine help.
The Spirit of truth is also the Spirit of love, for both love and truth are essential attributes of God. The love of the Father that is in the Son and the Spirit is now in us. By virtue of our baptism we are made worthy to take part in the love shared by the three persons of the Trinity. We are equally made worthy of doing the will of the Father as do the Son and the Spirit, for God is One. We are called, then, to freely love and freely obey the commandments of God. Empowered by the Spirit and Called by the Son, we are called to love and be loved by the Father, Son, and Holy Spirit. We are welcomed into the family of the Trinity. We are spiritual orphans no more.
