Pope Shenouda III
Regarding the kingdom of heaven of Christ, the Apostle says: "I charge you therefore before God and the Lord Jesus Christ, who will judge the living and the dead at His appearing and His kingdom" (2 Tim. 4: 1). About this heavenly kingdom, the Penitent Thief said: "Lord, remember me when You come into Your kingdom" (Lk. 23:43).
