Wrong on both counts and False Teaching...
It is written....For as 'in Adam' all DIE, so 'in Christ' all will be made Alive.....1 Corinthians 15:22
It is written...Just as the result of 'one trespass' (thru Adam) was condemnation for all men, so also the result of 'one act' of righteousness (thru Christ) was justification that brings LIFE for all men....Romans 5:18
And again written....For just as through the disobedience of 'the one man' (Adam) the many were made sinners, so also through the obedience of 'the one man'(Christ) the many will be made righteous....Romans 5:19
And again it is written....For since DEATH came through 'a man', the RESURRECTION of the dead comes also through 'a man.'......1 Corinthians 15:21
Jesus said to him,... I am the way, the truth, and the LIFE: no man comes to the Father, but by me....John 14;6
Mary wasn't on the Cross Jesus was.
So nope...Sin came thru Adam...Life thru Christ
....
You just keep telling yourself that...perhaps, to your own downfall, you may even come to believe it. Wouldn’t that be a sad day?
