John 16 is full of Jesus preparing His disciples for what's to come and encouraging them with the hope of the Holy Spirit. He tells them that they’ll face trouble and persecution, but they shouldn’t be surprised or discouraged because He’s going to send the Holy Spirit to guide and comfort them. Jesus explains that the Spirit will convict the world of sin, righteousness, and judgment, and that He will help them understand all that Jesus has taught them. He also reassures them that even though He’s going away, it’s for their good—because when He goes, the Spirit will come and be with them forever. Jesus acknowledges that they will grieve His departure, but their sorrow will turn to joy when they see Him again after His resurrection. He ends with a promise of peace, saying, “In this world you will have trouble. But take heart! I have overcome the world.” John 16 is about preparing for challenges, finding hope in the Holy Spirit, and holding onto peace in the midst of struggles because Jesus has already won the victory.
