Resurrection is obviously required in order for the saints to live again[10] and obtain “eternal life.” A common misnomer that Christians have with regard to the resurrection is that our bodies will become inherently immortal. This is largely due to the influence that Platonism has had on Christianity. Platonism’s “immortality of the soul” teaches the existence of a non-corporeal “soul” that is itself inherently immortal.
The Bible claims God alone possesses this quality. Man is dust, will return to the dust and only resurrection will provide him again with conscious life. After resurrection life will still be dependent on God. This is why Paul uses language concerning the Resurrection that indicates we will not possess immortality inherent to ourselves. The language he uses for our bodies after the Resurrection describes immortality as if it’s a garment to be worn over our flesh.
