“When you feel in your heart that the Lord ‘makes as if He would go further’ from your heart, from your thoughts, then constrain Him, the Merciful One, saying sincerely, ‘Abide with me:  for it is toward evening and the day’ of my spiritual life ‘is far spent; and He shall come in to tarry with thee;’ for He is merciful, and lets Himself be constrained.”

Saint John of Kronstadt
(see Luke 24:13-17, 28-29)
