According to the Biblical narrative, at the dawn of human history we find in the scriptures a group of individuals known as the sons of God (Genesis 6:2). The Orthodox Church identifies these sons of God found in the sixth chapter of Genesis as the righteous descendants of Seth, the son of Adam, and not fallen angels as other schools of thought teach. Though angels are referred to as sons of God in the book of Job, human beings who are led by the Spirit of God are also classified in the Bible as the sons of God (Romans 8:14). In contrast to the sons of God who serve the Lord faithfully, the Bible also identifies another type of people who walk not after the Spirit of God, and these rebellious individuals are known in the scriptures as the children of disobedience (Colossians 3:6).
In one of His many parables, the Lord Jesus likened the kingdom of heaven unto a man which sowed good seed in his field: but while men slept, his enemy came and sowed tares among the wheat, and went his way (Matthew 13:24-25). Jesus went on to explain this parable by stating that, the man who sowed the good seed is the Lord Himself, and that the field is the world. The good seed are the children of the kingdom, but the tares are the children of the wicked one (Matthew 13:37-38). St. Paul also illustrates that they which are of faith, the same are the children of Abraham (Galatians 3:7). Paul goes on to say that the prince of the power of the air (the devil) is the same spirit that now works in the children of disobedience (Ephesians 2:2). So, from these passages taken from the holy scriptures, it is clearly revealed that there are indeed only two types of people in this world: the children of God, and the children of the devil.
Concerning the resurrection of the dead, the second coming of Christ, and the separating of the sheep from the goats it is revealed that on the day of Judgment those on Christ’s right hand will receive an incorruptible body similar to the glorified body that Christ now has which was given to Him when He rose from the dead. Speaking on the resurrection of the righteous St. John writes, “Beloved, now are we the sons of God, and it doth not yet appear what we shall be: but we know that, when He shall appear, we shall be like Him; for we shall see Him as He is” (I John 3:2). As described in the scriptures Christ’s resurrected body is quite unique in that the Lord can not only pass through walls like a spirit (John 20:19), but His glorified body is also made up of flesh and bones which can be handled (Luke 24:39). So it would seem that at Christ’s resurrection His spirit and His body were merged into one, the same thing which will happen at the resurrection of the just when the soul’s of the believers in heaven will be reunited with their bodies that are in the graves. Like the glorified body of Jesus which is incorruptible and immortal, so too will the sons of God have a resurrected body not subject to aging nor decay and shall inherit the Kingdom of Heaven and enjoy everlasting life.
Now when it comes to the resurrection of the children of disobedience (who’s names were not found written in the book of life) scripture says that they will be cast into the lake of fire (Revelation 20:15). In addition to unrepentant sinners, death and hell will also be cast into the lake of fire, which the Bible says is the second death. Though scripture does not plainly express what type of body the damned will inherit, we can come to some conclusions as to the nature of the resurrected bodies of the children of disobedience by rightly dividing the Word of Truth. Since the Bible informs us that death will be cast into the lake of fire then this must mean that there is no life in hell. As Leviticus 17:11 tells us, the life of the flesh is in the blood. If there is no life in hell then there can be no blood in hell for there is life in blood. So, from this analysis we could strongly argue that in hell the children of disobedience will possess a body without blood. In the resurrection of the damned, not only will their souls be condemned, but their bodies will also suffer an eternal death, or as it is written: the second death.
In conclusion, from what we read in the New Testament, “The earnest expectation of the creature waiteth for the manifestation of the sons of God” (Romans 8:19). And as the beloved Apostle John wrote, “In this the children of God are manifest, and the children of the devil: whosoever doeth not righteousness is not of God, neither he that loveth not his brother. For this is the message that ye heard from the beginning, that we should love one another. Not as Cain, who was of that wicked one, and slew his brother. And wherefore slew he him? Because his own works were evil, and his brother’s righteous” (I John 3:10-12). So it would appear that the difference between a child of God, and a son of satan is that the sons of God are filled with love for God and their fellow man, whereas the children of disobedience are filled with disdain towards God and filled with hatred and jealousy towards God’s children. And knowing the persecutions that God’s people would suffer from the wicked people in this world, Jesus encouraged His followers by telling them that, “If the world hates you, keep in mind that it hated me first” (John 15:18).
