I just saw a sermon by Francis Chan where he shares about how when ministry leaders break our trust, it affects our ability to trust God. Skip to 15 minutes for this topic. That said, the whole sermon is worthy of watching and it reflects my recent life experience as well so I can vouch for this

This is a must see sermon for everyone who felt Witness Lee broke their trust.
