John 14:15-17 ESV
15 “If you love me, you will keep my commandments. 16 And I will ask the Father, and he will give you another Helper, to be with you forever, 17 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.
15 “Kung ako'y inyong minamahal ay tutuparin ninyo ang aking mga utos. 16 At hihingin ko sa Ama, at kayo'y bibigyan niya ng isa pang Mang-aaliw, upang makasama ninyo siya magpakailanman. 17 Ito ang Espiritu ng katotohanan na hindi kayang tanggapin ng sanlibutan; sapagkat siya'y hindi nito nakikita o nakikilala man. Siya'y nakikilala ninyo, sapagkat siya'y nananatiling kasama ninyo at siya ay mapapasa inyo.
Previously, Jesus pointedly taught that those who follow Him are obligated to show love for others (John 13:12–15, 34). That is the primary sign of faith to the outside world, is it not? (John 13:35). However here, He indicates that obedience to His commands is the primary sign of our love for Him. Neither a person can claim to know Christ and hate other Christians (1 John 4:20), nor he could claim to know Christ while disregarding His teachings (1 John 2:4).
Jesus commands is backed up with a promised Helper. When He asked it carries a more personal and mutual sense of asking. This implies that Jesus shares a relationship with God which transcends mere humanity. It also reinforces the idea that prayer is anchored in the Godhead, not intended to blindly grant us man’s wishes.
The Holy Spirit is our ‘Helper’. This can also be translated as a "comforter.” This is the same term, John will use later to describe Jesus as our ‘advocate’ in 1 John 2:1. This connection has meaning—Jesus will later point out that He is leaving behind His earthly ministry specifically so the Holy Spirit can act (John 16:7). The Holy Spirit, in a sense, does from the inside what Christ would do from the outside, namely: teach, convict, remind, and guide. In the following verse, Jesus will clarify that this Helper is the Holy Spirit, who is available only to those who believe Jesus (John 14:17).
