What does it mean to be a disciple who applies the entirety of Scripture to all aspects of life?
Brandon Scroggins conveys that being a disciple of every nation involves confessing and loving the Lordship of Christ. It's about being learners and lovers of Jesus, and teaching others to do the same. This involves taking the entirety of Scripture from Genesis to Revelation and applying it to every dimension of life. As Jesus said in Matthew 28, we should teach others everything that has been commanded, and that is a lifelong process.
According to Scroggins, observing everything Jesus said involves not only being regenerated or experiencing a change of heart but also living that change in every facet of life. This teaching is meant for every nation and every generation. The Gospel should not end with us, but should extend from one generation to the next. It requires a confession and love of the Lordship of Christ, and learning His ways in all areas of life, and teaching others to do the same.
2 Timothy 3:16-17 (NKJV): "All Scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness, that the man of God may be complete, thoroughly equipped for every good work."
