We must take refuge from this world. You can do this in spirit, even if you’re kept here in the body. You can at the same time be here and present to the Lord. Your soul must hold fast to God. You must follow after him in your thoughts. You must walk his ways by faith, not in outward show. . .Since God is our refuge, God who is in heaven and above the heavens, we must take refuge from this world in that place where there’s peace, where there’s rest from toil.

-St Ambrose of Milan
