How did the apostles receive guidance in the Book of Acts?

In the Book of Acts, we see the apostles seeking guidance through prayer and the reading of Scriptures. For instance, during their time in prayer after Jesus' ascension, Peter stands up and references Psalm 41 and Psalm 69 to make decisions concerning Judas’ replacement (Acts 1:15-20). The Holy Spirit plays a crucial role, guiding them in truth and empowering their mission. This reliance on prayer and Scripture highlights the importance of these elements in discerning God's will for the church.
