I think any book by Peter Walsh will be very helpful to you. He does not write from a Biblical base, but he is definitely supportive of faith/religion.
His first book is called, “It’s All too Much,” and the subtitle says, “An Easy Plan for Living a Richer Life with Less Stuff.”
Another book of his that I love is “Lighten Up” , and the subtitle says, “Love What You Have, Have What You Need, Be Happier With Less.”
I love his books! They really force me to think deeply about the life I want to live and compare it with the life I actually live. He gives all kinds of tools for eliminating all the “stuff” that prevents us from living the life we want to live.
This is so important for Christians, because most of us imagine a life of studying the Scriptures, praying, getting involved with our parish and doing good works–but many of us (me!) waste a lot of time watching TV, playing with our phones, shopping, spending money (and going into debt), etc. Peter’ Walsh’s books teach us how to live the life we truly want to live.
They’re very readable, too. Not boring. I copy quotes out of his books.
Hope this is helpful advice.
