Jesus began preaching that “the time is fulfilled, and the kingdom of God is at hand” (Mark 1:15). He also called for repentance and belief in the gospel in that same announcement (Mark 1:15).
In Mark 1:14–15, Jesus begins his public announcement in Galilee after John is arrested. His message has two main parts: a declaration and a demand. He declares that a decisive moment has arrived and that God’s reign is near. Then he calls for a response: people should turn around and trust the good news he is announcing. These verses follow Mark’s opening scenes that set the stage for Jesus’ ministry: John’s appearance and baptism, Jesus’ baptism, and his testing in the wilderness (Mark 1:1–13). With John removed from public activity, the narrative shifts to Jesus stepping forward and beginning to speak publicly.
Mark presents Jesus’ public message as beginning in a concrete historical moment: John has been arrested, and Jesus starts announcing God’s good news in Galilee (explicit in 1:14). The announcement is urgent. Jesus declares that a decisive moment has arrived (“the time is fulfilled”) and that God’s reign is near (“at hand”) (explicit in 1:15).
A careful answer keeps the immediate passage, the book's argument, and the whole-Bible storyline together, so the question is answered in context instead of as a detached idea.
Start with Mark 1:15, then read the surrounding section so the answer stays connected to the passage's flow.
