Chapter two shows that this Epistle, like 2 Timothy, 2 John, 3 John, and Jude, was written in the time of the church's degradation and apostasy. Hence, apostasy was the background of this book. The burden of the writer was to inoculate the believers against the poison of apostasy. God's salvation is to impart Himself in His Trinity into the believers that He may be their life and life supply. This is God's economy, God's plan. The apostasy distracted the believers from the economy of God by leading them into the human logic of puzzling philosophies. This did not lead them to partake of the tree of life, which gives life, but to participate in the tree of knowledge, which brings in death (Gen. 2:9, 16-17). Thus the serpent deceived and seduced Eve (Gen. 3:1-6). In order to inoculate against this death-poison, in his healing Epistle the apostle first prescribed the divine power as the strongest and most effective antidote. This provides the believers with all things related to the generating and supplying divine life (not the killing knowledge) and the God-expressing godliness (not the show of human wisdom). This rich divine provision, which is covered in detail in the succeeding verses (to v. 11), is more than sufficient to enable the believers to live a proper Christian life and overcome the satanic apostasy.
Divine denotes the eternal, unlimited, and almighty divinity of God. Hence, divine power is the power of the divine life, which is related to the divine nature.
