And I will ask the Father, and he will give you another Helper, to be with you forever, even the Spirit of truth, whom the world cannot receive, because it neither sees him nor knows him. You know him, for he dwells with you and will be in you. “I will not leave you as orphans; I will come to you.(John 14:16-18 ESV)
Everyone needs a helper, either physical or spiritual. However, the spiritual helper is more essential compared to the physical. Who among us could not use another helper? A Christian’s helper is the one and only Holy Spirit, the parakletos (the Greek word for advocate) and the counsellor.
But the Helper, the Holy Spirit, whom the Father will send in my name, he will teach you all things and bring to your remembrance all that I have said to you.(John 14:26 ESV)
Nevertheless, I tell you the truth: it is to your advantage that I go away, for if I do not go away, the Helper will not come to you. But if I go, I will send him to you.(John 16:7 ESV)
When the Spirit of truth comes, he will guide you into all the truth, for he will not speak on his own authority, but whatever he hears he will speak, and he will declare to you the things that are to come.(John 16:13 ESV)
Likewise, the Spirit helps us in our weakness. For we do not know what to pray for as we ought, but the Spirit himself intercedes for us with groanings too deep for words.(Romans 8:26 ESV)
