HP 266.5
(In Heavenly Places 266.5)
He [Christ] invites all to wear His yoke and learn His meekness and lowliness. He knows that it is positively necessary for them to do this. But no human being can wear the yoke of submission and obedience who does not learn daily in the school of Christ.... No one, whatever his supposed abilities, can bear the test of trial unless he is a student in the school of Christ.... (HP 266.5) MC VC
