The question is asking about a statement made by the disciples of Jesus in the book of Acts of the Apostles. They were asking God to show them which of two men he had chosen to replace Judas Iscariot, who had betrayed Jesus and died. The question wants to know who the two men referred to in the statement were.

The correct answer is option A, Justus and Matthias. These two men were chosen by the disciples as possible candidates to replace Judas. They were both qualified, but only one could be chosen. The disciples prayed to God to show them who should be chosen, and eventually, Matthias was selected.

It is important to note that the selection of Matthias was not a result of a popular vote or democratic process. The disciples believed that God would guide them in their decision, and they trusted in his wisdom to choose the right person for the job.

This question highlights the importance of prayer in decision making, especially when it comes to matters of faith. It also shows the role of the Holy Spirit in guiding believers to make the right choices. To learn more about this, please read the relevant sections of the recommended textbooks.
