Definition: The term "pf9" refers to the phrase in the Bible, which appears at the end of Acts 8:37: "Then when they had seen this, Paul called a meeting for all the believers, who were at the house where he was now staying." In this context, "pf9" likely refers to God's promise or revelation regarding his plans and actions. It suggests that he was preparing and announcing new things to these Christians as part of the same divine work. The phrase itself does not specify what they were saying in this specific instance.
