Your bible study shouldn't be a bunch of clones

One of the worst things you can do in order to grow in your faith is to remain completely homogenous.

Same culture.
Same education.
Same socioeconomic status.
Same life stages.
Same histories.

Ideally, those you go to church beside, and importantly, study the bible with should a different.

The group of people you intentionally study the bible beside should be diverse.

The ministers kid and the prodigal.
Those of different ages.
Those of alternate theologies and denominational backgrounds.
Those who feel like they've always been Christians and those who converted as young adults.

It's with this diverse mix that the bible can be best explored, theologies stretched and beliefs deepened.

It's with this diversity that you can see the bible through a viewpoint different than your own, hear how God speaks through others and better understand how He works through those unlike yourself.
