The man who sows for worldly results gets them, and everyone can see these and know them and appreciate them. The Christian, on the other hand, has very little that the world can appreciate. That is why the Way of Life is a difficult way — it is a life of faith.
When you enter upon it, you give up everything that the world treasures most, and it is inevitable that at times we shall experience a sense of loss. You start by giving up everything. What makes it still more difficult is that as you go on the demands do not lessen but become even greater and you have no immediate reward except a loving heart and an honest soul.” —D. Martyn Lloyd-Jones
