One of Toward the Goal's most referenced blogs is Operation Timothy, posted in June 2016. It's a great discipleship resource by CBMC under their Marketplace Ambassador Advancement System.
Now CBMC has released the Accountable App for smartphones. It's a pretty nifty app which links with the Marketplace Ambassador App and makes spiritual growth accountability easier.
The application allows you to create categories and then manage the level and method of accountability, either personally or between accountability partners. In the context of 2 Timothy 2:2 and Operation Timothy, accountabilities can also be shared on the smartphone app between your "Paul" and "Timothy".
The application allows multiple categories, each with individual entries, start date, reminders on or off, reminder time, specific days per week, and repeats.
It also allows tracking of your accountabilities with nice clean graphic displays.
The application is available on the Apple Store and Google Play and is a good addition to a spiritual growth toolkit.
