John Taylor (1752--1836), a pioneer Baptist preacher (mostly in Kentucky) was reputed to be warm and encouraging to young preachers, but could also be severe when he thought it warranted.
A young preacher at an associational meeting took his text from Ezekiel 47:3-5, the vision of the waters from the temple becoming a river. He divided his subject into four parts -- ankle-deep, knee-deep, loin-deep, deep enough for swimming. For about an hour he developed his first two points. Ankle-deep was repentance from sin. Knee-deep was assurance of salvation.
Taylor and other preachers, as was common in that day, were sitting behind him on the stand. Finishing his second division, the young preacher said, "Thirdly, we go a little deeper -— where the waters reached the loins."
At this point John Taylor straightened up, pointed his finger, and spoke up, "Young man, come ashore. You are deep enough, deep enough."
