On the narrow way. Few there be that find it — but few is not none. Wesley exhorts his hearers to enter in, even now, even against the world's flood.
Sermon 31 of 44 · 1750 · Matthew 7:13-14
Upon Our Lord's Sermon on the Mount, XI
A passage from the sermon
Enter ye in at the strait gate. There is no other way to life: he that seeketh another seeketh in vain. Broad is the way that leadeth to destruction; and many there be which go in thereat. But strait is the gate, and narrow is the way, which leadeth unto life; and few there be that find it.
Do not say, 'The way is so narrow, I cannot walk in it.' Christ has walked it before thee. Do not say, 'The gate is so strait, I cannot enter.' His grace is sufficient for thee. The men who have walked this way before thee were of like passions with thyself. Enter in now, while the gate is open, before the door be shut.
