A short but excellent exhortation to pray. Edifying from the first page to last. A few impactful quotes from the book:
“Reader, do you wish to find out whether you are a true Christian? Then rest assured that my question is one of the very first importance, – DO YOU PRAY?
“The habit of prayer is one of the surest marks of a true Christian. The converted people always pray”
“I have read the lives of many eminent Christians who have been on earth since the Bible days. Some of them, I see, were rich and some poor. Some were learned and some unlearned. Some of them were Episcopalians, some Presbyterians, some Baptists, some Independents, some Wesleyans. Some were Calvinists, and some Arminians. Some have loved to use a liturgy, and some to use none. But one thing, I see, they all had in common. They have all been men of prayer”
“But this I do say, – that not praying is a clear proof that a man is not yet a true Christian. He cannot really feel his sins. He cannot love God. He cannot feel himself a debtor to Christ. He cannot long after holiness. He cannot desire heaven. He has yet to be born again. He has yet to be made a new creature. He may boast confidently of election, grace, faith, hope, and knowledge, and deceive ignorant people. But you may rest assured it is all vain talk, if he does not pray”.
“Words said without heart are as utterly useless to our souls as the drum-beating of the poor heathen before their idols. Where there is no heart, there may be lip-work and tongue-work, but there is nothing that God listens to, – there is no prayer”
