The teaching set forth in Matthew chapters 24 and 25 is commonly identified as the Olivet Discourse and contains a detailed explanation of the end-times.
Mediator as applied to Christ, is borrowed from persons, whose office it is to reconcile such parties as are at variance, being as it were in the middle, betwixt both, soliciting the cause of each to the other, till they bring them to concord or agreement.
Christ in his humiliation was abased so low, as to be in subjection to the Father.
