Previously I said: [For many years I heard the term “I am a forgiven sinner”, so that’s not poor grammar but poor beliefs on the part of many Christians.]
You said: Are you saying that Jesus did not die for our sins? Our sins are not forgiven?
You said: Are you saying that Jesus did not die for our sins? Our sins are not forgiven?
Why would Jesus object to those, whose sins that he died for, to call themselves forgiven sinners, especially since it was sin that was forgiven?
Your stance makes absolutely no sense. Of course, we are adopted sons of God and heirs of the kingdom with Jesus Christ but that was only made possible by the shed blood of Jesus dying on the cross for our sins.
You might want to read John 3:16 to get a better understanding in regard to forgiven sin. That verse may help you.
