I would say that American poetry has always been a poetry of personal testimony.
If you reflect often on how His Atonement has changed you, and if you give thanks often, you will find that your witness of Him gains power to touch the hearts of others. When those you invite out of your own testimony feel that witness, they will come to accept Him as their Lord and Savior.
Confidence in others’ honesty is no light testimony of one’s own integrity.
Seek not the favor of the multitude; it is seldom got by honest and lawful means. But seek the testimony of few; and number not voices, but weigh them.
Testimony gives something to be interpreted.
Testimony should be a philosophical problem and not limited to legal or historical contexts where it refers to the account of a witness who reports what he has seen.
Testimony demands to be interpreted because of the dialectic of meaning and event that traverses it.
