Jude contrasts the outlook for "those who have been called" and "godless men". Those who God has called into faith are "loved by God" and "kept by Jesus Christ". Jude gives those of us who "share the salvation" encouragement to contend for and defend the faith against the godless men who "change the grace of our God into a license for immorality". Jude reminds us that the Lord delivers His people, and has "destroyed those who did not believe". These godless people will encounter "everlasting chains of judgement on the great Day" and will "suffer the punishment of eternal fire". They are described as clouds without rain, trees without fruit and uprooted, "for whom the blackest darkness has been reserved forever". He says the Lord is coming to judge and convict the ungodly. "But, dear friends, ..." you will be built up in your most holy faith and pray in the Holy Spirit, who will keep you in God's love as you wait on the mercy of our Lord Jesus to bring you eternal life. The last two verses of this letter are very encouraging to any who doubt their future outlook or may have any fear of being able to remain faithful enough to persevere.

 24To Him who is able to keep you from falling and to present you before His glorious presence without fault and with great joy— 25to the only God our Savior be glory, majesty, power and authority, through Jesus Christ our Lord, before all ages, now and forevermore!

3 john has three lessons for us: 1) practice hospitality and generosity, especially to missionaries or teachers of the Word 2) continue to walk in the truth, and 3) do what is right. 3 John is a letter to a fellow named Gaius who had a great reputation for always offering his hospitality and friendship to traveling missionaries and teachers. John says we should "support them so that we may become partners with them for the truth", for they are "traveling for the Lord". Gaius is an example of a faithful, selfless servant that we should strive to be like as we encounter opportunities to help those in God's ministry.

2 john encourages us to walk in the truth, walk in obedience, and walk in love. John says the truth lives in us and will be with us forever, just as His grace, mercy, and peace will continue to be with us. He then reminds us that "anyone who wanders away" from the teaching of Christ "has no relationship with God". Finally, "as you have heard from the beginning, His command is that you walk in love". Our love is demonstrated by walking according to His commandments. John concludes the letter with a warning not to associate with anyone who does not abide in the teaching of Christ, since in doing so would be participating in his evil deeds.

1 john 5 teaches that we achieve victory of the evil world through our faith in Jesus Christ, who has given us eternal life. John says that we may "know that we have eternal life" and that we can be "confident that He hears us whenever we ask for anything that pleases Him". He says that God's children don't make a practice of sinning because "God's Son holds them securely and the evil one cannot touch them". Jesus has "given us understanding so that we can know the true God" and live in fellowship with Him. Finally, John warns that we need to "keep away from anything that might take God's place in your hearts".

1 John 4 warns of false prophets who deny the truth about Jesus. We are reminded, however, that we are indwelled by the Holy Spirit, who is "greater than the spirit who lives in the world" and therefore we "have already won a victory over those people".
Next, John explains that God is love, and the love of God is in us "who confess that Jesus is the Son of God" . Since God so loved us that he sent his one and only Son in order for us to have eternal life, "we surely ought to love each other". Furthermore, John says, "those who love God must also love their Christian brothers and sisters".

1 John 3
We are God's children, so "let us show the truth by our actions".

1 john 2 teaches us that since Jesus is the atoning sacrifice for our sins, we are made complete in Him and can rightly claim to live in Him and consequently have the power and freedom to walk as He did. Through our relationship with Him, we are enabled by His grace to live a lifestyle in obedience to His word and commands. The truths of His word were evident in His life and walk, and therefore should be evident in our lives. As one begins this relationship with God, our old lifestyle of "darkness is passing and the true light is already shining", which is Christ in us. Our old worldly ways ("cravings of sinful man") pass away, "but the man who does the will of God lives forever". We are warned not to lose faith that Jesus is the Christ, which is "what you have heard from the beginning", even though some (antichrists) will try to persuade us to deny Him. Our indwelling Spirit of God teaches and guides us in truth and will faithfully remain in us, preserving us and allowing us to continue in confidence awaiting His return.
