I would highly recommend this book to you:
angeluspress.org/oscatalog/item/4092/rules-for-discerning-spirits
God won’t lead you astray in any way shape or form. But it’s highly possible we could misinterpret something - like St. Francis rebuilding a physical Church when Christ was speaking of the Church as in the Body of Christ. You would have to take a look at your answer and discern if it really is something that God wanted and is going to give Him Glory and benefit you (or whomever) spiritually.
While the devil can’t read your mind he’s very perceptive and he’s been watching and listening to you. He could possibly put things in your way as to make you think you’re prayer’s been answered in an effort to put your soul in danger - oh so subtly. The only way to determine this again is to try to discern the spirits. The book goes into this - it will tell you what signs to look for.
If you can PM me your email address I can send you a scanned copy of a sheet I got on a 5-day Ignatian retreat which will help you in making decisions - it may be of some use to you. It’s based upon St. Ignatius of Loyola’s spiritual exercises (as is the book I linked to).
God Bless,
