Personal independent Bible study is much like Press Maravich’s gunslinger drill. In dealing with your kids on a daily basis, or in helping other people in their walk with God, you will not most of the time, be doing Bible study while you are interacting with them. You will prepare before you meet, but you do not usually do the nuts and bolts of a study when you are meeting with them.
But the study you do, like the drill, prepares you to do a lot in working with your kids and your friends. Situations will arise in life and conversations that will remind you of things you have studied. You will be able to speak to those issues from a foundation of your personal Bible study.
I was asked a couple of years ago if Bible study was training for ministry, it is not all, but it is the core. Everything else is dependent on study.
