We are commissioned to send forth the good news of the Gospel message, to preach and teach that message, for that is the sacred scriptures' used by the Holy Spirit to save lost sinners
No, the gospel is not the sacred Scriptures. Scripture contains the gospel account. But the gospel existed prior to the writing of the NT.
How would one even know of that truth without scriptures though?
How do you know Scripture is true?
When I say sacred scriptures refer to entire canonized books. all 66 of them
That is even more wrong than your first claim.
The gospel is not the 66 books of the Bible.
One does not have to read the entire Bible to be saved.
One does not have to know the entire Bible to be saved.
One does not even have to believe the entire Bible to be saved.
BUT one does have to believe the gospel, for it is the power of God to salvation.
The Author who inspired them can confirm their truth
So God can confirm the Bible is true but He is unable to confirm the gospel of Jesus Christ told to another person to be true?
How did God confirm the Bible is true?
To some degree the entire Bible itself is the Gospel of the Person and work of the Lord Jesus, the Promised Messiah of Genesis to the Messiah who came, and shall one day come again
No. You are talking
about the gospel. The gospel is more narrow.
The Bible IS about Jesus, about redemption, and about the gospel. But the Bible is not the gosoel itself.
I ask again, if I share the gospel of Jesus Christ with a man, he repents and believes the gospel of Jesus Christ, then why is he not saved?
