Understanding God's greatness in the book of Hebrews
Like the first point, we could go on and on what makes the books of scripture unique. To think that the infinite great God, who dwells in eternity (Isaiah 57:15; Jude 1:24-25) has stooped down so-to-speak and chosen to communicate via words is truly remarkable.
Passages such as Exodus 24:4; Jeremiah 1:1-5; Habakkuk 2:3; 2 Timothy 3:16-17 and 2 Peter 1:21 describe the character of scripture as "the voice of God". When the scriptures are unpacked and preached (much like would had been the Epistle to the Hebrews), the Spirit of God speaks through them. The scriptures as written words were composed by the Prophets and Apostles under the Divine inspiration of the Holy Spirit (2 Timothy 3:16; 2 Peter 1:21). As these books were originally given, they are God's words (1 Thessalonians 1:5; 2 Thessalonians 2:13). The church is built upon the foundation of the scripture - which is described as the foundation of the prophets and apostles, with Jesus Christ being the chief cornerstone (Ephesians 2:20).
1 Peter 3:18 states - "For Christ also died for sins once for all, the just for the unjust, so that He might bring us to God, having been put to deathin the flesh, but made alive in the spirit." So many other texts speak of the greatness of God revealed through the greatness of salvation. Salvation is not only viewed as referring to the salvation and reconciliation of believers to God, but the restoration and transformation of the created order (Romans 8:21-25). This of course does not mean that there will be universal salvation, but what it does entail is the bringing about of a New Heavens and Earth at Christ's appearing (2 Peter 3:13) as well as all those who by grace through faith believed on Him.
