The Bible does not only contain the fruit of the knowledge of good and evil, which causes death if eaten, but also the fruit of life, which grants immortality.
Since the words of the Bible are spiritual, both the fruit of the knowledge of good and evil and the fruit of life are spiritual fruits, and spiritual fruits are ultimately spirits.
Therefore, it implies that there is a spirit that causes death and a spirit that grants immortality.
Ultimately, the fruit of life refers to the Spirit of God who overcomes ‘self,’ overcomes the devil, and overcomes the power of death.
