Regeneration

The necessity of regeneration arises from the fact that man by the fall has become dead in sin. Spiritual life is extinct, and, therefore, if any are saved, they must be regenerated. Life cannot spring from death. Life is a gift of God in all cases. He breathed into man, when his body was formed out of the clay, the breath of life. It would be as reasonable to believe that the organized body could inspire itself with life, as that the dead soul can perform acts of spiritual life. - Archibald Alexander
