what does the bible say?
The Bible does not prescribe, or even mention, journaling. Thus it is certainly not a requirement, but many believers find it to be a useful and fruitful habit. Writing out our prayers and recording God's answers, addressing God through a sort of Christian diary, jotting down spiritual truths and times when we see God at work, and keeping a written record of important sermon notes or teachings from a book, are all helpful and valuable forms of Christian journaling. We are instructed to seek wisdom (Proverbs 4) and to focus and be steadfast (Proverbs 4:20–26). Writing down our thoughts or notes can help us to do this.
