How does this verse connect to God's holiness in Isaiah 6:3? Verse at a glance • Isaiah 6:3: “And they called out to one another: ‘Holy, holy, holy is the LORD of Hosts; all the earth is full of His glory.’” • 1 Peter 1:16: “for it is written: ‘Be holy, because I am holy.’” Bridging the gap: from vision to vocation • Isaiah’s vision shows the seraphim declaring God’s unrivaled, three-fold holiness—His complete moral purity and utter separateness from all creation. • Peter quotes Leviticus but echoes Isaiah’s scene: the God who is inherently holy now calls His people to reflect that holiness in every area of life. • What Isaiah saw in the throne room becomes, through Christ, the believer’s daily mandate. Key themes connecting the two verses • God’s incomparable nature – “Holy, holy, holy” (Isaiah 6:3) stacks the adjective to its superlative height; Peter’s citation reminds us that the same God speaks across both Testaments. • Revelation leads to transformation – Isaiah is overwhelmed, confesses sin, receives cleansing (Isaiah 6:5-7). – Peter urges believers to respond similarly: abandon former ignorance and live set-apart lives (1 Peter 1:14-15). • Holiness overflows into mission – Isaiah’s cleansing is followed by the commission “Here am I. Send me!” (Isaiah 6:8). – Peter writes to elect exiles scattered in the world, charged to proclaim God’s excellencies (1 Peter 2:9). • Divine glory fills creation – The seraphim declare, “all the earth is full of His glory.” – Holy living makes that invisible glory visible in a fallen world (Matthew 5:16; Philippians 2:15). Practical takeaways for today • Stand in awe: spend unhurried time pondering the God Isaiah saw; reverence fuels obedience. • Embrace cleansing: Christ’s blood purifies our consciences (Hebrews 9:14), enabling the holiness Peter commands. • Live distinct: holiness touches speech, relationships, entertainment—everything (1 Thessalonians 4:3-7). • Reflect His glory: a holy life turns daily routines into steady declarations of “Holy, holy, holy.” Supporting passages • Leviticus 11:44-45; 19:2 – the original call to be holy • Psalm 99:3, 5, 9 – worship built on God’s holiness • Revelation 4:8 – the heavenly echo of Isaiah’s vision • Hebrews 12:14 – pursue holiness “without which no one will see the Lord” |
