Note 7 at Ac 16:27: The reason the jailer was going to kill himself was because of the Roman law that imposed the death penalty on the jailer if his prisoners escaped. Rather than face execution, he decided to kill himself. The Lord used Paul to point out to this jailer what God had done for him. Without Paul's intervention, this jailer would have died. Likewise, the Lord has called us to tell this hopeless world that God has provided salvation for them. If we don't share the Gospel, many people will destroy their lives too.

Note 8 at Ac 16:27: This jailer nearly killed himself and went into a Christ-less eternity when God had provided a great miracle just for him. He just supposed that there was no way out of this one. Likewise, Satan has convinced many people that their situations are hopeless when the truth is that God has already provided their miracles for them. Faith is what allows people to perceive God's miracles instead of their problems.
