1 Corinthians 15:45 So also it is written, “The first man, Adam, became a living soul.” The last Adam became a life-giving spirit.
One has presented the above scripture as proof that the judgment day had already begun in the first century. Evidently, the thought is being presented that since Jesus is stated as having become a life-giving spirit, that this means that the judgment day had already begun when the words were spoken. — Acts 17:31; Matthew 25:31-46.
There is no doubt that Jesus had been already raised as a life-giving spirit being. He was indeed put to death in the flesh, but made alive in the spirit. He was no longer a human, which is defined as being a little lower than the angels, the elohim, but he was at that time exalted above the angels. This does not mean that Jesus had already begun to exercise his authority toward to bring the judgment of the world in first century, while leaving Satan as the deceiver of the world. (2 Corinthians 4:4; Revelation 12:9) Thus, his exercise of authority as king and judge as described in parable of the sheep and goats is held off until after Satan is abyssed. (Revelation 20:1-3) Then, the kingdom will expand to fill the whole earth, and thereby bless all the heathen with a new day of judgment. (Genesis 22:18; Daniel 2:35,44; Isaiah 2:2-4; John 12:47,48; Revelation 20:1-5; 22:2).
However, God at that time was selecting out a few from the world who become the seed of Abraham with Jesus (Galatians 3;29); these were indeed reckoned as made alive (Romans 6:11) as children of God (Romans 8:14) in this age, but they were still waiting for Christ’s return for their final reward. — Romans 8:23; Hebrews 9:28.
There is nothing in 1 Corinthians 15:45 that negates that there is yet a future day when God will judge the world by means of the one whom He has ordained. — Acts 17:31.
