My approach to this may be a little different.
We have a loving Creator in Heaven who wishes us to come to Him and to be saved from our sins. "God so loved the world that He gave His only begotten Son...." Our heavenly father has made every provision for us to take this offer of salvation. The Holy Scriptures are the means by which we can know of His mercy. Yes there are many writings but I believe that the Bible as we know it contains all that is necessary to aquaint us with the information needed. It's not a question of what is right or wrong but what is needed for us to know. We do read that "Holy men of God spake as they were moved by the Holy Spirit".
I trust absolutely Holy Scripture as we know it and believe that God guided the compilers to prepare our Bible as it is.
