What does the Bible say about the fullness of time in Galatians 4?

In Galatians 4:4, it is mentioned that 'when the fullness of the time was come, God sent forth His Son, made of a woman, made under the law.' This 'fullness of time' signifies a specific, God-ordained moment in history where the plan of redemption would be fulfilled. It encapsulates the culmination of God's preparations, which involved everything from the promises made to Abraham to the establishment of the Old Covenant. The coming of Christ was not arbitrary but rather a critical part of God's sovereign timetable.
