Maturity in Christ means we have become “adult sons,” occupied with Christ. “Occupation with Christ” is living life in the Grace Place, filled with the Holy Spirit on a consistent basis, by the consistent volitional exercise of 1 John 1:9 (if and when necessary), and the inculcation of Bible doctrine.
The ascent to spiritual maturity involves the literal transformation from human viewpoint to divine viewpoint – (God’s Word – Bible doctrine), which is an ongoing process until the Lord calls us home.
Maturity may also be defined as “Advancing to the high-ground of the spiritual life.” Living in the Grace Place is the “Life more abundant” that Christ came to Earth to give us (John 10:10).
