He must remember that he is subject to trials of faith and character which he might not otherwise have had. He simply must believe that if he does his share towards the fulfilment of his duties the results pass out of his hands and become God's concern. He must therefore leave it to God to arrange the ways and means whereby he will be able to discharge his responsibilities. He must have enough faith to believe that he will not be let down. It often happens to one on this path that what he greatly needs does not come to him when he prematurely asks for it but only comes when the need is actually ripe. This combination of doing his bit and then trusting in God will carry him through all his difficulties.
