Commentaries:
Robertson's Word Pictures (NT)
Follow after peace (eirhnhn diwkete). Give peace a chase as if in a hunt.
With all men (meta pantwn). Like Paul's use of diwkw with eirhnhn in Romans 14:19 and his to ec umwn (so far as proceeds from you) in Hebrews 12:18. This lesson the whole world needs including Christians.
Sanctification (agiasmon). Consecration as in I Thessalonians 4:7; Romans 6:19, etc.
Without which (ou xwriv). Ablative case of the relative with xwriv (post positive here). About seeing God compare Matthew 5:8 where we have kaqaroi.
