Gal. 4:4-7 But when the fullness of time had come, God sent forth his Son, born of woman, born under the law, to redeem those who were under the law, so that we might receive adoption as sons. And because you are sons, God has sent the Spirit of his Son into our hearts, crying, “Abba! Father!” So you are no longer a slave, but a son, and if a son, then an heir through God.
In the fullness of time, God sent His Son. He sent His Son for redemption. We were all slaves of sin, Christ came in the fullness of time to redeem or purchase us from sin. We are His purchased possession. He also came to adopt us into His family. We are not only no longer slaves,we have become sons. We are children of God by faith in Christ. Fullness also speaks to us about the anointing of the Holy Spirit. This is what we were purchased for, so that we can partake of God through the person of the Holy Spirit. Fullness also speaks to us about inheritance. We have become heirs of God through faith. This is what Christmas is, it is about the fullness of time and the blessing that was purchased for us. Here are some thoughts from the JFB Commentary.
“God does nothing prematurely, but, foreseeing the end from the beginning, waits till all is ripe for the execution of His purpose. Had Christ come directly after the fall, the enormity and deadly fruits of sin would not have been realized fully by man, so as to feel his desperate state and need of a Savior. Sin was fully developed. Man’s inability to save himself by obedience to the law, whether that of Moses, or that of conscience, was completely manifested; all the prophecies of various ages found their common center in this particular time: and Providence, by various arrangements in the social and political, as well as the moral world, had fully prepared the way for the coming Redeemer. God often permits physical evil long before he teaches the remedy.”
Could it be that we are coming into another one of those ‘fullness of time’ moments in history? Could it be the darkness has run its course and the time of the harvest of redemption has come? The Spirit of sonship that resides in every believer is crying out that His Second Coming is upon us. As we celebrate Christmas, we are waiting in joyful anticipation of His second Advent.
