2 Peter 1:16-21

For we did not follow cunningly devised fables when we made known to you the power and coming of our Lord Jesus Christ, but were eyewitnesses of His majesty. For He received from God the Father honor and glory when such a voice came to Him from the Excellent Glory: “This is My beloved Son, in whom I am well pleased.” And we heard this voice which came from heaven when we were with Him on the holy mountain.

And so we have the prophetic word confirmed, which you do well to heed as a light that shines in a dark place, until the day dawns and the morning star rises in your hearts; knowing this first, that no prophecy of Scripture is of any private interpretation, for prophecy never came by the will of man, but holy men of God spoke as they were moved by the Holy Spirit.

Psalm 19:1-3

The heavens declare the glory of God; And the firmament shows His handiwork.

Day unto day utters speech, And night unto night reveals knowledge.

There is no speech nor language

Where their voice is not heard.

1 Peter 3:15

But sanctify [b]the Lord God in your hearts, and always be ready to give a defense to everyone who asks you a reason for the hope that is in you, with meekness and fear;

Ephesians 4:4-6

There is one body and one Spirit, just as you were called in one hope of your calling; one Lord, one faith, one baptism; one God and Father of all, who is above all, and through all, and in you all.

1 Timothy 4:16

Take heed to yourself and to the doctrine. Continue in them, for in doing this you will save both yourself and those who hear you.
