Scenario 1: Wrong thing, Right reason
A church is having a fundraiser and the congregation is split into groups for friendly competition. The leader of one group decides to rip and burn CDs of praise and worship songs and sell them to the congregation with the money going towards the church pot. Should Federal piracy laws get thrown out the window because its being done for Jesus?
Scenario 2: Right thing, Wrong reason
A Christian woman has a male friend who is unsaved. She lets him know that she's praying for him to change his life--which she is actually doing--and puts him on to some Christian media to point him in the right direction. She truly does want this man to get saved... because she's convinced that she's supposed to marry him, and the only way she can do that--and remain true to God's word--is if he becomes a Christian. Does it matter that she's checking for him, once her efforts help to win a soul for the kingdom?
