Then He appointed twelve, that they might be with Him and that He might send them out to preach.
2 Corinthians 11:13-15 When considering matters of life, death, and eternity, nothing could be more important than authority. That is, who do we believe, and why? The world is full of people claiming to speak for God, but credentials are of the utmost importance. There are false apostles today just as there were in the first century (2 Corinthians 11:13-15).
The common denominator of apostolic authority in the first century was having seen and heard Jesus Christ in person: “How shall we escape if we neglect so great a salvation, which at the first began to be spoken by the Lord, and was confirmed to us by those who heard Him” (Hebrews 2:3). Spiritual and divine authority began with Christ and continued through those He appointed and sent out. Their authority was confirmed by “signs and wonders and mighty deeds” (2 Corinthians 12:12)—confirmation that was lacking among false apostles who sought to establish themselves through deceit and counterfeit means.
The reason the New Testament epistles are trustworthy is because they were written by those called to speak for Christ.
Without such apostolic inspiration there can be no infallible revelation.
