“Because strait is the gate, and narrow is the way, which leadeth unto life, and few there be that find it.”
Matthew 7:14 — Greek Interlinear
Church Fathers on Matthew 7:14
The Lord had warned us above to have a heart single and pure with which to seek God; but as this belongs to but few, He begins to speak of finding out wisdom. For the searching out and contemplation whereof there has been formed through all the foregoing such an eye as may discern the narrow way and strait gate; whence He adds, 'Enter ye in at the strait gate.'
Though it be hard to do to another what you would have done to yourself; yet so must we do, that we may enter the strait gate.
Otherwise; This third precept again is connected with the right method of fasting, and the order of discourse will be this; 'But thou when thou fastest anoint thy head;' and after comes, 'Enter ye in at the strait gate.'
