But when they thought that they were delivered, then was their fear increased, whence it follows, “And seeing him walking upon the sea, they were troubled, saying, It is a vision, and through fear they cried out.” For this the Lord ever does; when He is to rescue from any evil, He brings in things terrible and difficult.
