Adam called His Wife's name - Life Source

When God explained to Adam about the promised seed through the woman and the problems that would arise for him through the fall Adam turned to the woman and called her the Life Source. He should have immediately believed God and it would have been counted for righteousness like it was with Abraham. Gen 15:6. The naming of Eve as Life source was a denial of the gospel promise and this brought great suffering to Christ and manifested in the sacrificial process to reveal this.
