No sin found : "in Christ".

[Behold]

So you've found one verse out of many that says to be saved you must do this one thing: "as many will call on the Name of the Lord, shall be saved".

I quoted only one.
Here are a few more...

“For He made Him who knew no sin to be sin for us, that we might become the righteousness of God in Him.” + Acts 16:30-31 “Sirs, what must I do to be saved?” So they said, “Believe on the Lord Jesus Christ, and you will be saved"""

"To him that worketh not but BELIEVETH on Jesus, God gives to them the power to become the Son's of God.""


""""For by grace you have been saved through faith. And this is not your own doing; it is the gift of God, not a result of works""""

"""""if you confess with your mouth that Jesus is Lord and believe in your heart that God raised him from the dead, you will be saved."""

"""""""Whoever believes in the Son has eternal life""""
