“But the salvation of the righteous is of the Lord: he is their strength in the time of trouble.”
Psalm 37:39 KJV
I have waited for thy salvation, O LORD! Thou art my rock, and my fortress, and my deliverer; my God, my strength, in whom I will trust; my buckler, and the horn of my salvation, and my high tower; Lord of my salvation!
… at midnight Paul and Silas prayed, and sang praises unto God: and the prisoners heard them.
And suddenly there was a great earthquake, so that the foundations of the prison were shaken: and immediately all the doors were opened, and every one’s bands were loosed.
And the keeper of the prison awaking out of his sleep, and seeing the prison doors open, he drew out his sword, and would have killed himself, supposing that the prisoners had been fled.
But Paul cried with a loud voice, saying, Do thyself no harm: for we are all here.
Then he called for a light, and sprang in, and came trembling, and fell down before Paul and Silas,
and brought them out, and said, Sirs, what must I do to be saved?
And they said, Believe on the Lord Jesus Christ, and thou shalt be saved, and thy house.
And they spake unto him the word of the Lord, and to all that were in his house.
Acts 16:25-32 KJV
