Given the circumstances of those to whom Peter wrote his second letter, it’s not hard to see that in 2 Peter 1:12-21, the apostle wrote as he did. The false teachers were undermining his authority as an appointed apostle of the Lord and also downplaying the divinity of Jesus. In these verses, Peter puts them in their place and highlights something of his own first-hand experience as an eye and earwitness of the glory of Jesus and the certainty of God’s Word.
