 In verse 5, we read that God's plan was to adopt us as sons and daughters through Christ, according to the purpose of his will. In Galatians 4, 4 and 5, Paul writes, 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. The fullness of all time came in the incarnation, death, and resurrection of Jesus.
