A) Here we are in Jude Verse 20. After all of that encouragement, Jude says, "But you, beloved, build yourselves up in your most holy faith." One of the great takeaways is how much compassion and love Jude had for the people of God. He tells them to build themselves up in their most holy faith. By that, he means to strengthen themselves, similar to what happened to David in 1 Samuel, Chapter 30, where everything seemed lost, and the Bible says that David strengthened himself in the Lord. That’s what he’s talking about. We do that by spending time with the Lord.

B) Jude also tells us to pray in the Holy Spirit. What does that mean? Could it mean praying in tongues? Sure. Does it have to be tongues? No. We already know that John the Apostle, when he wrote the Book of Revelation, was in the Spirit on the Lord’s Day. Being in the Spirit means not being in the flesh. It means not being centered and connected with our own desires, needs, or things that encourage the old man to stick around. It means being involved in the spiritual things that God has established by the power of His Spirit.

C) Verse 21 tells us to keep ourselves in the love of God. What’s amazing is that people don’t realize how easy it is to not keep yourself in the love of God. In fact, we’re encouraged to stay in that love, which is difficult because so many people and things come towards us that make us want to throw mud. The fact of the matter is that God was compassionate to us when we were jerks, and we need to be compassionate to other people too.

D) Jude gives a reason for us to stay in the love of God: we are awaiting the mercy of our Lord Jesus Christ to bring us eternal life. In a sense, we have eternal life now, but as you know, we have not yet fully realized that eternal life. We need to put on an immortal body to get there. As we wait for the mercy of Jesus to bring us eternal life, we need to stay in the love God has established.
