Adam and Eve were God's magnificent creation gone awry, and they were the first human beings to have teeth. That is because human beings did not exist in physical form until Adam and Eve were created. He was God's grand experiment, and he failed the test of obedience because he placed his physical circumstances ahead of his spiritual life. He decided that having food was more important than having life for all eternity. He did not know that the loss of life would continue for six thousand years, and that everyone would be affected by his decision. He also did not know that when the time came to enter into eternal life, his body would still be in the earth and full of corruption.
Adam's body did not resurrect when the dead in Christ resurrected, nor did he resurrect when the Old Testament martyrs resurrected. He is the first son of God who needs to see eternity, and therefore, his body must be resurrected. He also needs to see the millennial reign of Christ. When and how he will be resurrected is unknown, but what is known is that he must be resurrected. He must see the light of day, and he must see life eternal.
