This makes it clear that no other writings, no matter how godly the pastor, theologian, or denominational church they may come from, are to be seen as equal to or completing the Word of God. The Bible is all that is necessary for the believer to understand the character of God, the nature of man, and the doctrines of sin, heaven, hell, and salvation through Jesus Christ. Paul’s words to the Galatians indicate the seriousness of delivering a message outside the Bible: “If we or an angel from heaven should preach a gospel other than the one we preached to you, let him be eternally condemned!”
Nililinaw ng talatang ito na walang ibang aklat o sulat ng kahit sinong pastor o teologo saan mang denominasyon ng iglesya sila galing, ang maaaring ituring na kapantay o katulad ng Salita ng Diyos. Naglalaman ang Bibliya ng lahat ng kinakailangan ng isang mananampalataya upang maunawaan niya ang mga katangian ng Diyos, ang kalikasan ng tao, ang doktrina tungkol sa kasalanan, langit, impiyerno at ang doktrina ng kaligtasan sa pamamagitan ni Hesu Kristo.
