How do we know the sufficiency of the gospel is true?
Answered in 1 source
The sufficiency of the gospel is affirmed through Scripture's teaching that it alone has the power to save.
The sufficiency of the gospel is confirmed by the apostolic teachings found in Scripture. Paul assures us that the gospel is the power of God for salvation, and he intentionally chose to present it without lofty speech to ensure that faith depends not on human wisdom but on divine power (1 Corinthians 2:5). This confirms that Scripture provides everything necessary for understanding the gospel, and it teaches that regeneration and spiritual discernment are provided by the Holy Spirit, making the gospel effective in the lives of believers. Our confidence in its sufficiency is rooted in the promises and truth of God's Word.
