John 8:31-36

Overview & Insights
“If you abide in my word… you will know the truth, and the truth will set you free.” (John 8:31–32)
The reaction of many of the Jewish authorities with whom Jesus has been speaking is to believe in him (v. 30), and the remainder of the discourse is focused on this group of “believers.” The prediction that they will realize later who Jesus is (v. 28) appears to be coming true even before they lift him up on the cross. It sounds, and it is, too good to be true. Their faith is not genuine (cf. 2:23–25). Jesus has directed their attention toward the future, but they will have none of it. The present is good enough for these “believers,” and they are satisfied with their current relationship to God.

Questions preachers ask
What freedom does Jesus promise?
To those who hold to his word Jesus promises the truth that frees; everyone who sins is a slave to sin, but “if the Son sets you free, you will be free indeed” (John 8:31–36). It is a cornerstone text for Reformation Day.
