Revelation 14:3

No one could learn the song except the 144,000 who had been redeemed...your father is training you for a part the angels cannot sing, and his classroom is the school of sorrows. In the darkest he is composing your song. In the valleys he is tuning your voice. In the storms he is deepening your range. In the rain he is sweetening your melody. In the cold he is giving your notes expression. And as you pass at times from hope to fear, he is perfecting the message of your lyrics.
