Charles Spurgeon Commentary Hebrews 3:10

"Wherefore I was displeased with this generation, And said, They do always err in their heart: But they did not know my ways;" — Hebrews 3:10 (ASV)

Wherefore I was grieved with that generation, and said, They do always err in their heart; and they have not known my ways.

They err; they always erred in their heart. God is very lenient towards errors of judgment—errors of the head. But to err in the heart—this is the very essence of erring and very provoking to the Most High; and for this always to be so, after having tasted the bitter fruit of erring—after having known God's angers on account of previous errors—oh, this was sad! They do always err in their heart.

The foundation of sin, however, often lies in ignorance: They have not known my ways. Ignorance can never be of any benefit to us.

That the soul be without knowledge is not good. But ignorance of God is the persistent source of the errors of the heart. All thy children shall be taught of the Lord, is a very gracious promise, and when it is fulfilled, the errors are rectified by the grace of God.
