"I do not deny that a man may pray without heart and without sincerity. I do not for a moment pretend to say that the mere fact of a person's praying proves everything about his soul. As in every other part of religion, so also in this: there may be deception and hypocrisy. 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 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."
—J.C. Ryle (from A Call to Prayer)
Prayer can be a struggle, sometimes for seasons. There's a lot to unpack from the quote above, but I'll leave that for you to think on and end with what scripture says:
"Rejoice always, pray without ceasing, give thanks in all circumstances; for this is the will of God in Christ Jesus for you." (1 Thessalonians 5:16-18)
