He who is the faithful witness to all these things says, "Yes, I am coming soon!" Amen! Come, Lord Jesus! (Revelation 22:20 NLT)
One day Christ will come again to call His children out of this world. Both the dead bodies of His saints, as well as Christians living at that moment will be translated into His presence. On that day sin, death, crying, pain, sorrow, suffering, injustice, separation, sickness, etc., will be over forever for them. That's a great reason to pray like John, "Come, Lord Jesus!"
