For the battles we have to fight, the conflicts of faith with unbelief, and righteousness with aggressive iniquity, an inspiration is needed like that conveyed to Israel in the peal of the silver trumpets. Have we any means of assurance resembling that which was to animate the Hebrews when the enemy came upon them? Even the need is often unrecognised. Many take for granted that religion is safe, that the truth requires no valour of theirs in maintaining it, and the Gospel of Christ no spirited defence. The trumpet is not heard because the duty to which all Christians are called as helpers of the Gospel is never considered. Messages are accepted as oracles of God only when they tell the trustful of safety and confirm them in easy enjoyment of spiritual privilege and hope. One kind of trumpet peal alone is liked--that which sounds an alarm to the unconverted, and bids them prepare for the coming of the Judge. But there are for all Christians frequent calls to a service in which they need the courage of faith and every hope the covenant can give. At the present time no greater mistake is possible than to sit in comfort under the shadow of ancient forms and creeds. We cannot realise the value of the promise given to genuine faith unless we abandon the crumbling walls and meet our assailants in the open ground, where we can see them face to face, and know the spirit with which they fight, the ensigns of their war. There is no brave thinking now in those old shelters, no room to use the armour of light. Christianity is one of the free forces of human life. Its true inspiration is found only when those who stand by it are bent on securing and extending the liberties of men. The trumpets that lift to heaven the prayers of the faithful and fill the soldiers of the Cross with the hope of victory can never be in the hands of those who claim exclusive spiritual authority, nor will they ever again sound the old Hebrew note. They inspire those who are generous, who feel that the more they give the more they are blessed, who would impart to others their own life that God's love to the world may be known. They call us not to defend our own privileges, but to keep the way of salvation open to all, to prevent the Pharisee and the unbeliever from closing against men the door of heavenly grace.
