Read Acts 16:25-40
The jailer's conversion is as sudden as it is unexpected: and yet the result is the same. His heart, now open to the gospel, leads him immediately to be concerned for Paul and his companions (he washes their wounds) and immediately gets baptised. Not only do all his household follow suit, but they rejoice with him at the good news that is now theirs.
Paul experienced the joy of seeing his jailer become his brother because he was ready to praise God and preach the gospel (singing songs while shackled?! Inmate preaching to a prison governor?!).
Are there places you go, or situations you find yourself in where you don't feel as though the gospel is relevant? Or people that you're hesitant to share the gospel with because you don't know how they'll react?
Consider how you would have reacted, had you been in Paul's situation: beaten unjustly, chained in the most secure cell in the prison – and all of it an illegal violation of your rights as a citizen! Maybe your vision of God is too small? Maybe your expectations of God are too low?
Ask God to fill you with the confidence and boldness to trust Him in every place and with everyone.
