Read John 14:15-21
[Jesus said] “And I will ask the Father, and he will give you another Advocate, who will never leave you. He is the Holy Spirit, who leads into all truth. The world cannot receive him, because it isn’t looking for him and doesn’t recognize him. But you know him, because he lives with you now and later will be in you.” – John 14:16-17 (NLT)
When Satan, the Accuser, comes against us, the Holy Spirit is our Advocate and Defender. When the world comes against us, the Holy Spirit advocates for us by working through us to show God’s righteousness. When our own sins call us to disobedience, the Holy Spirit calls to mind the incredible love and sacrifice our Savior has made for us, and draws us back to confession and repentance. Christ has not left us orphaned; we have an Advocate.
