“And if you address as Father the One who impartially judges according to each man’s work, conduct yourselves in fear during the time of your stay upon the earth” (1 Peter 1:17).
Thomas Watson says:
“Labor to get the fear of God into your hearts. As a levee embankment keeps out the flood waters, so the fear of the Lord keeps out moral uncleanness. Those who lack the fear of God, lack a bridle that should check them from sin. Bernard calls holy fear, janitor animae, the door-keeper of the soul. As a nobleman’s porter stands at the door, and keeps out vagrants, so the fear of God stands and keeps sinful temptations from entering.”
(Thomas Watson, The Ten Commandments, p 161)
