17 But remember, dear friends, that the apostles of our Master, Jesus Christ, told us this would happen: "In the last days there will be people who don't take these things seriously anymore. They'll treat them like a joke, and make a religion of their own whims and lusts." These are the ones who split churches, thinking only of themselves. There's nothing to them, no sign of the Spirit! 20 But you, dear friends, carefully build yourselves up in this most holy faith by praying in the Holy Spirit, staying right at the center of God's love, keeping your arms open and outstretched, ready for the mercy of our Master, Jesus Christ. This is the unending life, the real life! 22 Go easy on those who hesitate in the faith. Go after those who take the wrong way. Be tender with sinners, but not soft on sin. The sin itself stinks to high heaven.
