Hebrews 6:7

“For the earth which drinketh in the rain that cometh oft upon it, etc..] Here the apostle illustrates what he had before been speaking of, by a simile taken from the earth, to which men in general answer, who are of the earth; earthy and unregenerate men and carnal professors are of earthly minds; they are like the earth when it was rude and without form, and cursed by God; and are as insensible as the earth: but the earth is particularly distinguished into that which is fruitful, and which is unfruitful; and the former is spoken of in this verse, to which true believers in Christ agree; who are the good ground, into which the seed of God's word is received, and brings forth fruit; these are…”

It is to show the consequences of not making a proper use of all the privileges which Christians have, and the effect which would follow should those privileges fail to be improved.

The design is to show that “if” Christians should become like the barren earth they would be cast away and lost. Which drinketh in the rain - A comparison of the earth as if it were “thirsty” - a comparison that is common in all languages. That cometh oft upon it - The frequent…”

“6:7-8 ground: Good, productive land is an image of blessing, contrasted with the curse of unproductive land that bears thorns and thistles. To burn such a field is an image of judgment (2 Sam 23:4-7; Isa 10:17; 33:12; Ezek 19:12-13; Matt 3:10).”
