Wise words from Martin Luther:
I have exhorted so often, and still exhort, that all who wish to be saved pray diligently, as Christ Himself commands us to pray (Matt. 9:38), that God may grant us faithful laborers and pastors who are sincere and adhere to the Word. Then if God be willing, there will be no danger. For the pulpit can and must alone preserve Baptism, Sacrament, doctrine, articles of faith, and all estates in their purity. However, if we neglect to pray and if we anger God with our security, weariness, and ingratitude, He will send us, instead of St. Paul and all upright pastors, stupid asses who will snatch away both Sacrament and Word, and we lose everything, both in the doctrine and the office.
