Throughout the Church there is a complaint of defeat. The Church has so little power over the masses, or the educated classes. Powerful conversions are comparatively rare. The fewness of holy, consecrated, spiritual Christians, devoted to the service of God and their fellowmen, is felt everywhere. The power of the Church for the preaching of the gospel to the heathen is paralysed by the scarcity of money and men; and all owing to the lack of the effectual prayer which brings the Holy Spirit in power, first on ministers and believers, then on missionaries and the heathen. Can we deny it that the lack of prayer is the sin on account of which God's presence and power are not more manifestly seen among us?
4. _God Himself will discover the hidden sin._--We may think we know what the sin is: it is only God who can discover its real deep meaning. When He spoke to Joshua, before naming the sin of Achan, God first said, "They have transgressed My covenant which I commanded them." God had commanded (vi. 19) that all the booty of Jericho, gold and silver and all that was in it, was to be a devoted thing, consecrated unto the Lord, and to come into His treasury. And Israel had broken this consecration vow: it had not given God His due; it had robbed God.
It is this we need: God must discover to us how the lack of prayer is the indication of unfaithfulness to our consecration vow, that God should have all our heart and life. We must see that this restraining prayer, with the excuses we make for it, is greater sin than we have thought; for what does it mean? That we have little taste or relish for fellowship with God; that our faith rests more on our own work and efforts than on the power of God; that we have little sense of the heavenly blessing God waits to shower down; that we are not ready to sacrifice the ease and confidence of the flesh for persevering waiting on God; that the spirituality of our life, and our abiding in Christ, is altogether too feeble to make us prevail in prayer. When the pressure of work for Christ is allowed to be the excuse for our not finding time to seek and secure His own presence and power in it, as our chief need, it surely proves that there is no right sense of our absolute dependence upon God; no deep apprehension of the Divine and supernatural work of God in which we are only His instruments, no true entrance into the heavenly, altogether other-worldly, character of our mission and aims, no full surrender to and delight in Christ Jesus Himself.
If we were to yield to God's Spirit to show us that all this is in very deed the meaning of remissness in prayer, and of our allowing other things to crowd it out, all our excuses would fall away, and we should fall down and cry, "We have sinned! we have sinned!" Samuel once said, "As for me, God forbid that I should sin against the Lord in ceasing to pray for you." Ceasing from prayer is sin against God. May God discover this to us. (Note A.)
5. _When God discovers sin, it must be confessed and cast out._--When the defeat at Ai came, Joshua and Israel were ignorant of the cause. God dealt with Israel as a nation, as one body, and the sin of one member was visited on all. Israel as a whole was ignorant of the sin, and yet suffered for it. The Church may be ignorant of the greatness of this sin of restraining prayer, individual ministers or believers may never have looked upon it as actual transgression, none the less does it bring its punishment. But when the sin is no more hidden, when the Holy Spirit begins to convince of it, then comes the time of heart-searching. In our story the combination of individual and united responsibility is very solemn. The individual: as we find it in the expression, "man for man"; each man felt himself under the eye of God, to be dealt with. And when Achan had been taken, he had to make confession. The united: as we see it in all Israel first suffering and dealt with by God, then taking Achan, and his family, and the accursed thing, and destroying them out of their midst.
