"Woe to the world for the causes of sin. These stumbling blocks must come, but woe to the man through whom they come! " Matt 18:7.
If you know the Pastor or church leader has stolen from the church, cheated on their wife or done other things, are you held accountable for continuing to support them? Even if they have not repented? I am amazed when I read of corruption in a church and yet some members of the church still support the Pastor or church leader.
