John Gill Commentary Mark 4:22

"For there is nothing hid, save that it should be manifested; neither was [anything] made secret, but that it should come to light." — Mark 4:22 (ASV)

For there is nothing hid
In these parables, and figurative expressions used by Christ,

which shall not be manifested ,
sooner or later, to his disciples:

neither was any thing kept secret ;
any doctrine of the Gospel, or mystery of the kingdom:

but that it should come abroad ;
it was designed to be published in all Judea, and afterwards, throughout the whole world, for the benefit of God's chosen ones, to their conversion, comfort, and edification:

wherefore it becomes the ministers of the Gospel to keep back nothing that may be profitable to the churches, nor shun to declare the whole counsel of God; but faithfully dispense the mysteries of grace, and commend the truth to every man's conscience, without any fear of men, or dreading the effects and consequences of things:

since nothing is declared in the word, or made known, but with a design to be published to others, to answer some divine end and purpose; (See Gill on Matthew 10:26).
