Love is, however, closely associated with faith and hope. Faith, as we have seen, is theologically the formative and appropriating power by which man makes his own the spirit of Christ. But ethically it is a form of love. The Christian character is formed by faith, but it lives and works by love. A believing act is essentially a loving act. It is a giving of personal confidence. It implies an outgoing of the self towards another--which is the very nature of love. Hope, again, is but a particular form of faith which looks forward to the consummation of the good. The man of hope knows in whom he believes, and he anticipates the fulfilment of his longings. Hope is essentially an element of love. Like faith it is a form of idealism. It believes in, and looks forward to, a better world because it knows that love is at the heart of the universe. As faith is the special counteragent against materialism in the present, so hope is the special corrective of pessimism in regard to the future. Love supplies both with vision. Christian hope, because based on faith and prompted by love, is no easy-going complacence which simply accepts the actual as the best of all possible worlds. The Christian is a man of hope because in spite of life's sufferings he never loses faith in the ideal which love has revealed to him. 'Tribulation,' says St. Paul, 'worketh patience, and patience probation, and probation hope.' Hope has its social aspect as well as its personal; like faith it is one of the mighty levers of society. Men of hope are the saviours of the world. In days of persecution and doubt it is their courage which rallies the wavering hosts and gives others {198} heart for the struggle. Every Christian is an optimist not with the reckless assurance that calls evil good, but with the rational faith, begotten of experience, that good is yet to be the final goal of ill. 'Thy kingdom come' is the prayer of faith and hope, and the missionary enterprise is rooted in the confidence begotten of love, that He who has given to man His world-wide commission will give also the continual presence and power of His Spirit for its fulfilment.
