What should I do in order to be saved?

Acts 16:25-32… And at midnight Paul and Silas prayed, and sang praises unto Elohim: and the prisoners heard them. 26 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. 27 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. 28 But Paul cried with a loud voice, saying, Do thyself no harm: for we are all here. 29 Then he called for a light, and sprang in, and came trembling, and fell down before Paul and Silas, 30 And brought them out, and said, Sirs, what must I do to be saved?

31 And they said, Believe on the Yahshua the Messiach, and thou shalt be saved, and thy house. 32 And they spake unto him the word of the YHWH, and to all that were in his house.

Rom 11:26-27… And so all Israel shall be saved: as it is written, There shall come out of Sion the Deliverer, and shall turn away ungodliness from Jacob: 27 For this is my covenant unto them, when I shall take away their sins.

Prov 28:9…He that turneth away his ear from hearing the law, even his prayer shall be abomination.

To add to this, it has been said that “Once saved always saved”, but Yahshua says…But he that shall endure unto the end, the same shall be saved. Matt 24:13-15
