Samuel Rutherford:

I urge upon you…a nearer communion with Christ and a growing communion. There are curtains to be drawn by in Christ that we never saw, and new foldings of love in Him. I despair that ever I shall win to the far end of that love, there are so many plies in it; therefore dig deep, and sweat, and labour, and take pains for Him, and set by so much time in the day for Him as you can: He will be won with labour.

- Samuel Rutherford, The Loveliness of Christ
