What does it mean that God sent forth His Son 'in the fullness of time'?

'In the fullness of time,' as mentioned in Galatians 4:4, highlights the idea that God's timing is precise and purposeful. It indicates that there was a specific moment in redemptive history when God deemed it appropriate for His Son to enter the world. Throughout the history of Israel, God had been progressively revealing His plan through the prophets and the Law, culminating in the incarnation of Jesus Christ. The phrase illustrates that God is sovereign over history, orchestrating events to fulfill His divine purpose. This also extends beyond the birth of Christ; it reassures believers that God operates with perfect timing in their own lives, working out His will according to His divine schedule.
