"In the evening of life, we will be judged on love alone."

"The Lord's love is not earned; it is given freely to those who seek Him."

"Silence is God's first language; everything else is a poor translation."

"Where there is no love, put love, and you will find love."

"Never let fear stop you from chasing your dreams."

"Courage is being afraid but doing it anyway."

"Sometimes you gotta do what you gotta do."

"Sometimes you have to be the monster to stop the monsters."
