Biblical explanation
Jesus clearly recognized the authority of the Old Testament Scriptures. After His resurrection, He referred to: "the law of Moses, and the prophets, and the psalms" Luke 24:44, KJV Jesus also repeatedly appealed to Scripture as authoritative. The apostles continued this practice. Paul described the Jews as having been entrusted with: "the oracles of God." Romans 3:2, KJV Peter provides an especially important New Testament example. Referring to Paul's writings, he says: "some things hard to be understood... which they that are unlearned and unstable wrest, as they do also the other scriptures." 2 Peter 3:16, KJV Peter's wording places Paul's writings in connection with the category of Scripture. Scripture does not describe a single meeting where a group of leaders sat down and created the biblical canon. The recognition of particular books as authoritative developed within the biblical community, while the authority of Scripture itself is presented as originating with God. This distinction is important: A council does not make God's Word inspired. Rather, people recognize and receive writings because they are believed to possess divine authority. The exact historical development of the canon involves questions beyond what Scripture itself records.
Key takeaway
Salvation is entirely by grace through faith in Christ. His atoning sacrifice, heavenly ministry, and intercession are the foundation of assurance; obedience, Sabbath faithfulness, and loving service are the fruit of a redeemed life, never a way to purchase acceptance with God.
