The end of all things is near: With the coming of Christ, the "last days" predicted by the Old Testament prophets had begun (see 1:10–12). The next event in God’s plan to save people is the second coming of Christ. His return will bring an end to the world as we know it. This end could come at any time. Therefore, Christians must always be ready for it (see also Philippians 4:5; James 5:8; Revelation 1:3; 22:10).
