Revelation 22:20-21 He who testifies to these things says, “Yes, I am coming quickly.” Amen. Come, Lord Jesus. 21 The grace of the Lord Jesus be with all. Amen.
The second coming of Jesus Christ is the source of hope in both its related but distinct doctrine of the rapture and the fact that Christ's second coming plays such a huge role in scripture. Titus 2:13 reminds us - "looking for the blessed hope and the appearing of the glory of our great God and Savior, Christ Jesus."
Is it worth living for and serving the Lord? Do the dissapointments of life and opposition of the enemy determine the horizon of faith? Certainly not! The horizon of the faith life is the fact that Christ has risen and coming again! At the end of what is perhaps the most important chapter in the Bible on the subject of Christ's resurrection and second coming, we read in 1 Corinthians 15:58 "Therefore, my beloved brethren, be steadfast, immovable, always abounding in the work of the Lord, knowing that your toil is not in vain in the Lord."
The second coming of Jesus Christ gives us purpose for living, hope for tomorrow and finally the tone of preparation in our evangelism.
The tone of preparation reverberates like a might echo through the cavernous truth of Christ's second coming in the scriptures. This idea of "being prepared" or "being alert" supplies the chief evangelistic component to our Christian faith. Note Matthew 24:44 "For this reason you also must be ready; for the Son of Man is coming at an hour when you do not think He will." Also too, Hebrews 2:3 "how will we escape if we neglect so great a salvation? After it was at the first spoken through the Lord, it was confirmed to us by those who heard."
Though the above reasons are only a thumbnail sketch, the hope is that the reader has seen the practical, relevant meaning of the truth of Christ's second coming to the 21st century Christian. I close with the familiar, one worded prayer at the end of 1 Corinthians 16:22 "maranatha" ("Come Lord"! or "the Lord cometh!").
