The authority of the Holy Scripture, for which it ought to be believed, depends not on the testimony of any man or church, but wholly upon God its author (who is truth itself). Therefore it is to be received because it is the word of God.
2 Thes 2:13
But we ought always to give thanks to God for you, brothers beloved by the Lord, because God chose you as the first fruits to be saved, through sanctification by the Spirit and belief in the truth.
2 Tim 3:16
All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness
2 Pet 1:19-21
19 And we have the prophetic word more fully confirmed, to which you will do well to pay attention as to a lamp shining in a dark place, until the day dawns and the morning star rises in your hearts, 20 knowing this first of all, that no prophecy of Scripture comes from someone's own interpretation. 21 For no prophecy was ever produced by the will of man, but men spoke from God as they were carried along by the Holy Spirit.
