How do we know God's glory is important?

The importance of God's glory can be seen throughout Scripture, where it is often the purpose behind God's actions, creation, and salvation. Everything God does is for His glory, as stated in passages like Ephesians 1:3-14, where each aspect of salvation is described as being 'to the praise of His glory.' Moreover, the glory of God defines not only His actions but also the ultimate objective of humanity's existence—to know Him and to glorify Him. Therefore, recognizing and prioritizing the glory of God is foundational to our understanding of the gospel and Christian living.
