What do you do with the person who wants to pull out of volunteering because they “don’t feel like they’re doing it for the right reasons”.
It’s hard because motives do matter. We want people to do things with good gospel-centred Jesus-honouring motives.
But notice something in that quote… they’re aware of what they’re motives should be. If you asked them something like, “What motives do you think you should have?” they could probably answer you.
So if you know the good motives you should have, and you realise that you don’t have those motives… determine to have different motives. Enter that struggle.
Encourage people to persever in serving Jesus even when they don’t feel like it. Encourage them to set about altering their motives like they would alter any other aspect of sin or struggle with temptation.
