Martyn Lloyd-Jones
Evangelism must start with the holiness of God, the sinfulness of man, the demands of the Law and the eternal consequences of evil.

A genuine Gospel-faith has nothing selfish about it – it never makes a man think only of his own salvation. It stirs him up, on the contrary, to concern about the souls of others. I always suspect that those who care nothing whether their brethren are saved or not, must in reality be ignorant or thoughtless about their own state.
