I. Nature, in all her departments, is a system of mutual accommodation. Every object affords hospitality to every other object. Nature places before us, in the kind shelter which the larger and more richly endowed objects afford to the smaller and poorer, a silent picture of what should be our own conduct in the intercourse of human life; and in the added beauty and charm which the exercise of this grace of hospitality imparts to the objects that bestow it, she teaches us that by receiving strangers we too may be entertaining angels unawares. As nature is ever defeating the plans of selfishness by making all her objects mutually dependent, none being allowed to live entirely for itself, so God, by the arrangements of His providence, is breaking down all human monopolies and enforcing a wide hospitality, allowing no man to live for himself alone.
II. In the plan of religion His intention is still more manifest. The growth of His kingdom on earth is like that of a mustard tree, which, springing from the smallest seed, develops into the grandest form, covering the earth with its shadow and lodging the birds of the air among its boughs, protecting the poorest and feeblest things which men may despise.
III. From every lonely, hungry soul Jesus seeks hospitality, standing at the door without, patiently waiting for the opening of it; and when He is welcomed in, there is a mutual feeling of love, and the Guest becomes a generous Host. And what His thoughts of hospitality to the race whom He has come to seek and redeem are is strikingly seen in that beautiful parable where the feast is spread, and the servants are sent first to individuals favoured by fortune and then to the poor and the outcast, to bid them all come, for all things are ready.
