Jesus warned of four signs preceding his return: global deception, turmoil, persecution, and personal betrayal. These signs have been occurring for 2,000 years like birth pains that increase over time, signaling we're in a different season. Jesus didn't give us these signs to speculate about timing, but to live faithfully through them. When we ignore his return, we lose urgency, sobriety, and hope. The gospel isn't just that Jesus came once - he's coming back to completely remove sin and dwell with his people forever.
