Mission can’t be planned beyond the next step because people are unpredictable. We don’t know who will respond or how. In many industries you can match inputs and outputs. But in Christian ministry there’s never a neat correlation between inputs and outputs. You can’t say, ‘If I do these Bible studies with these people then I can guarantee that this is what they’ll be like at the end.’ Mission can’t be planned beyond the next step because people are unpredictable.
And mission can’t be planned beyond the next step because God is sovereign. It’s God who opens hearts to the gospel. We can’t know or predict ahead of time who will become Christians. It’s God’s work to grant faith and repentance. And often he surprises us.
A gret reminder for all servants of the gospel by Tim Chester. Read the entire blog post in full. It's the first in a series on mission planning. Great title.
