Can someone explain how Faithlife Connect works and its importance?
Have a look at Faithlife's own publicity and then come back with any specific questions.
I agree with Mike that it is best to review what FL has written. Here is the cliff notes:
FC allows you to rent/subscribe to the features. You lose access once you stop subscribing. As with Amazon Prime, there are "additional benefits" to a subscription, but the primary focus is the features.
Save a bundle on books.
