I have a particular time set aside to write my blog posts (in the morning after running, showering and studying). If something comes up that interferes with that (like bloodwork at 7:15), I have a hard time fitting it in. (And I realize at 4:30, I never wrote the post.)
Bible study is the same way. I have a time set aside to study. But it's not the same time every day.
Monday through Friday it's 6:30-ish (-Ish because my run doesn't always take the same amount of time, and occasionally I take a day off.)
Saturday, it's morning-ish. I sleep in a little on Saturday.
On Sunday, it's afternoon-ish (after church, lunch and a nap J )
Not planned down to the minute, but a regular, predictable, habitual study time.
Scheduling your study-
Ensures it will get done
Cements it as a priority
Builds a habit with incredible benefits
The schedule has to fit you
Studying at night would never work for me. Too many distractions. I'm tired. Our evenings don't follow a routine. But it may just your thing.
Long stretches don't work for me either. About twenty or thirty minutes is my maximum. However, some folks prefer a once a week marathon session.
It's always flexible. Move your study time until you find a good time slot.
When is your scheduled study time?
