Hebrews 12:14
14Follow after peace with all men, and the sanctification without which no man will see the Lord,
Wesley: follow peace with all—this branch concerns neighbors; holiness concerns God. Not following after all holiness is the direct way to fall into sin of every kind.
Arminians detect a double pursuit: peace and holiness, both to be followed. Without holiness none see the Lord—a warning for hearers who must pursue sanctification, not a bare slogan over the already secure.
Calvin: men naturally shun peace by studying their own interest; strive with all care, forgetting offenses. Yet peace with the ungodly must not approve vice—holiness together with peace. Without holiness none see the Lord; we see God with eyes renewed after His image.
Peace is pursued; holiness is the bond of union with God. Seeing the Lord requires the holiness He works in His people.
