John 16:18

Then said some of his disciples among themselves, What is this that he saith unto us, A little while, and ye shall not see me: and again, a little while, and ye shall see me: and, Because I go to the Father?

18 They said therefore, What is this that he saith, A little while? we cannot tell what he saith.

Ver. 18. We cannot tell what he saith] We know here but in part; the greatest part of our knowledge is the least part of our ignorance, saith one. Man's heart, saith another, may be compared to a vessel, the means to a pipe; the Spirit of God to the wheel that beats the water into the pipe; the minister is the servant that opens the cock. (August.) And then the reason why we know but in part is, either the cock always runs not, or not always in the same measure; and sometimes our vessels are filled with other things (as the apostles here were with worldly grief and the conceit of an earthly kingdom), and so they run over; and usually our vessels run over, and lose what we received by the means.
