Jesus knows how hard life can be, and the types of persecution believers can face. He warns us that it’s coming so that we’ll be ready and we won’t fall away when it happens (1-4). We especially need to understand what is coming because Jesus won’t be here physically to help us anymore (4-5). Unfortunately, the disciples are more concerned about Jesus being gone than where He is going and what it means (5). Do you get the feeling that He wants them to be happy for Him? Anyway, it’s to our advantage that He’s going away, because He’s sending the Spirit to help us and to guide us (7, 13). The Spirit will help us to understand God’s truth (12-15), and the Spirit will make the ministry of evangelism possible (8-11) by convicting the world of sin, righteousness and judgment. Of sin, because we are all sinners in need of a Savior:
Romans 6:23 “For the payoff of sin is death, but the gift of God is eternal life in Christ Jesus our Lord.”
Of righteousness, because Jesus’ death, resurrection and ascension show that what Jesus said was true and that righteousness can only come through Him:
Acts 2:22-36 “Men of Israel, listen to these words: Jesus the Nazarene, a man clearly attested to you by God with powerful deeds, wonders, and miraculous signs that God performed among you through him, just as you yourselves know—this man, who was handed over by the predetermined plan and foreknowledge of God, you executed by nailing him to a cross at the hands of Gentiles…This Jesus God raised up, and we are all witnesses of it. So then, exalted to the right hand of God, and having received the promise of the Holy Spirit from the Father, he has poured out what you both see and hear…Therefore let all the house of Israel know beyond a doubt that God has made this Jesus whom you crucified both Lord and Christ.”
Romans 5:1 “Therefore, since we have been declared righteous by faith, we have peace with God through our Lord Jesus Christ.”
And judgment, because judgment is assured, on both Satan and those who don’t believe:
Revelations 20:10-15 “And the devil who deceived them was thrown into the lake of fire and sulfur, where the beast and the false prophet are too, and they will be tormented there day and night forever and ever. Then I saw a large white throne and the one who was seated on it; the earth and the heaven fled from his presence, and no place was found for them. And I saw the dead, the great and the small, standing before the throne. Then books were opened, and another book was opened—the book of life. So the dead were judged by what was written in the books, according to their deeds. The sea gave up the dead that were in it, and Death and Hades gave up the dead that were in them, and each one was judged according to his deeds. Then Death and Hades were thrown into the lake of fire. This is the second death—the lake of fire. If anyone’s name was not found written in the book of life, that person was thrown into the lake of fire.”
Evangelism would be impossible if it weren’t for the work of the Holy Spirit in the world!
