Get a first draft done so you can type “the end” instead of getting stuck halfway through and never finishing it. You can always go back and fix what you’ve written. But you can’t fix a blank page.
I think God puts you where he wants you to be and we all have the opportunity to minister to others wherever we are. You don’t need a church or an altar. A cup of coffee and a friendly greeting might suffice.
You could be ministering to someone every day and not even know it.
