Pray that the saints would apprehend in their experience of prayer that prayer is a warfare but praise is a victory, and would learn to advance from fighting prayer to victorious praise (Acts 16:25-26, 29-34).
Acts 16:25-26—And about midnight Paul and Silas, while praying, sang hymns of praise to God; and the prisoners were listening to them. And suddenly there was a great earthquake, so that the foundations of the prison house were shaken. And instantly all the doors were opened and everyone’s bonds were unfastened.
Acts 16:29-34—And the jailer asked for lights and rushed in; and trembling, he fell down before Paul and Silas. And leading them outside, he said, Sirs, what must I do to be saved? And they said, Believe on the Lord Jesus, and you shall be saved, you and your household. And they spoke the word of God to him together with all those in his house. And he took them with him in that very hour of the night and washed their wounds. And he was baptized immediately, he and all his household. And he brought them up into his house and set a table before them; and he exulted because he had believed in God with all his household.
