I am continuing to read through Spurgeon's Treasury of David. It gives me great fellowship with saints of the past. When I read what people 200, 400, 1000 years ago wrote about their struggles, it humbles me.

That's particularly true as I was reading the words of long-ago saints wrote about regarding sin in our hearts (Psalm 67). Here is one, almost 200 years old that convicted me:

If I regard iniquity in my heart, the Lord will not hear me. The very supposition that “if he regarded iniquity in his heart, the Lord would not hear him, “implies the possibility that such may be the state even of believers; and there is abundant reason to fear that it is in this way their prayers are so often hindered, and their supplications so frequently remain unanswered. Nor is it difficult to conceive how believers may be chargeable with regarding iniquity in their heart, even amidst all the solemnity of coming into the immediate presence of God, and directly addressing him in the language of prayer and supplication. It is possible that they may put themselves into such a situation, in a state of mind but little fitted for engaging in that holy exercise; the world, in one form or another, may for the time have the ascendancy in their hearts; and there may have been so much formality in their confessions, and so much indifference in their supplications, that when the exercise is over, they could not honestly declare that they really meant what they acknowledged, or seriously desired what they prayed for. A Christian, it is true, could not be contented to remain in a state like this; and, when he is awakened from it, as he sooner or later will be, he cannot fail to look back upon it with humiliation and shame. But we fear there are seasons in which believers themselves may make a very near approach to such a state; and what then is the true interpretation of prayers offered up at such a moment? It is in fact saying, that there is something which, for the time, they prefer to what they are formally asking of God; that, though the blessing which they do ask may be for a time withheld, yet they would find a compensation in the enjoyment of the worldly things which do at the moment engross their affections; and that, in reality, they would not choose to have at that instant such an abundant communication of spiritual influence imparted to them, as would render these worldly objects less valuable in their estimation, and would turn the whole tide of their affections towards spiritual things… The Christian may sometimes betake himself to prayer, to ask counsel of God in some perplexity regarding divine truth, or to seek direction in some doubtful point of duty; but, instead of being prepared fairly to exercise his judgment in the hope that, while doing so, the considerations that lie of the side of truth will be made to his mind clear and convincing; he may have allowed his inclinations so to influence and bias his judgment towards the side of error, or in favour of the line of conduct which he wishes to pursue, that when he asks counsel it may only be in the hope that his previous opinion will be confirmed, and when he seeks direction it is in reality on a point about which he was previously determined… Another case is, I fear, but too common, and in which the believer may be still more directly chargeable with regarding iniquity in his heart. It is possible that there may be in his heart or life something which he is conscious is not altogether as it should be””some earthly attachment which he cannot easily justify””or some point of conformity to the maxims and practices of the world, which he finds it difficult to reconcile with christian principle; and yet all the struggle which these have from time to time cost him, may only have been an effort of ingenuity on his part to retain them without doing direct violence to conscience””a laborious getting up of arguments whereby to show how they may be defended, or in what way they may lawfully be gone into; while the true and simple reason of his going into them, namely, the love of the world, is all the while kept out of view. And, as an experimental proof of how weak and inconclusive all these arguments are, and at the same time how unwilling he still is to relinquish his favourite objects, he may be conscious that in confessing his sins he leaves them out of the enumeration, rather because he would willingly pass them over, than because he is convinced that they need not be there; he may feel that he cannot and dare not make them the immediate subject of solemn and deliberate communing with God; and, after all his multiplied and ingenuous defences, he may be reconciled to them at last, only by ceasing to agitate the question whether they are lawful or not. Robert Gordon, D.D., 1825.
