You don’t see in the following verses that Jesus said the truth will save believers from the slavery to sin?
Then said Jesus to those Jews which believed on him, If ye continue in my word, then are ye my disciples indeed;
And ye shall know the truth, and the truth shall make you free.
They answered him, We be Abraham's seed, and were never in bondage to any man: how sayest thou, Ye shall be made free?
Jesus answered them, Verily, verily, I say unto you, Whosoever committeth sin is the servant of sin.
And the servant abideth not in the house for ever: but the Son abideth ever.
If the Son therefore shall make you free, ye shall be free indeed. (John 8:31-36).
You left out what Jesus says about these "Jews which believed on Him." You stopped at verse 36.
John 8:43 Why do you not understand My speech? Because you are not able to listen to My word.
44 You are of your father the devil, and the desires of your father you want to do.
John 8:47 He who is of God hears God's words; therefore you do not hear, because you are not of God."
There is another cause and effect sentence where Jesus says the effect "not hearing God's words" is
caused by because you are not of God.
Wait a minute, it began with Jews which believed in Him. How can Jesus say they do not hear God's words?
I assume that the "believe in Him" was a superficial belief. That is why Jesus said (8:31) "If you
abide in My word, you are My disciples indeed."
Abide means = to stay (in a given place, state, relation or expectancy): - abide, continue, dwell,
endure, be present, remain, stand, tarry.
Jesus said:
Mat_10:22 . . . But he who
endures to the end will be saved.
Jesus knew these Jews would not endure to the end.
John 6:64 But there are some of you who do not believe." For Jesus knew from the beginning who they were who did not believe . . .
