Camboie could you help in understanding the way the light blindness is removed?Light came to Israel, ( the darkness could not comprehend what light is. John 1:5.)
Even though all the miracles Jesus did confirmed He was that light, nobody was able to believe in Him, to fulfil who believed the report of the Lord ?
To whim was the arm of the Lord revealed, when their eyes are blinded and their hearts hardened) the new covenant is God taking the stony heart our and replacing with a heart of flesh.) then they would not be converted and healed.
Faith comes by hearing ( this testimony) and even though the sound went into all the earth, it was also testified all the day long the Lord had stretched His hand out to a disobedient gainsaying people( Israel.)
John 12:36 While ye have light, believe in the light, that ye may be the children of light. These things spake Jesus, and departed, and did hide himself from them.
37 But though he had done so many miracles before them, yet they believed not on him:
38 That the saying of Esaias the prophet might be fulfilled, which he spake, Lord, who hath believed our report? and to whom hath the arm of the Lord been revealed?
39 Therefore they could not believe, because that Esaias said again,
40 He hath blinded their eyes, and hardened their heart; that they should not see with their eyes, nor understand with their heart, and be converted, and I should heal them.
Romans 10:16 But they have not all obeyed the gospel. For Esaias saith, Lord, who hath believed our report?
17 So then faith cometh by hearing, and hearing by the word of God.
Romans 10:18 But I say, Have they not heard? Yes verily, their sound went into all the earth, and their words unto the ends of the world.
19 But I say, Did not Israel know? First Moses saith, I will provoke you to jealousy by them that are no people, and by a foolish nation I will anger you.
20 But Esaias is very bold, and saith, I was found of them that sought me not; I was made manifest unto them that asked not after me.
21 But to Israel he saith, All day long I have stretched forth my hands unto a disobedient and gainsaying people.
NOW look at Mark 3 for CONTEXT.
Christ did miracles in front of Israel, they had those hardened hearts( which is why they could never believe in Christ)
The Pharisees we are told, took counsel against Christ, how they could destroy Him. ( JESUS WITHDREW HIMSELF FROM THEM.)
Mark 3:5 And when he had looked round about on them with anger, being grieved for the hardness of their hearts, he saith unto the man, Stretch forth thine hand. And he stretched it out: and his hand was restored whole as the other.
6 And the Pharisees went forth, and straightway took counsel with the Herodians against him, how they might destroy him.
7 But Jesus withdrew himself with his disciples to the sea: and a great multitude from Galilee followed him, and from Judaea,
Knowing now that Christ cant be known by Israels hardened hearts, and in fact they wanted to murder Him for these miracles, it is very easy to see why the people are charged by Christ to not make Him known.
Mark 3:11 And unclean spirits, when they saw him, fell down before him, and cried, saying, Thou art the Son of God.
12 And he straitly charged them that they should not make him known.
