The Unbelief of the people

John 12:37-50 

Even after Jesus had performed so many signs in their presence, they still would not believe in him. 38 This was to fulfill the word of Isaiah the prophet:

“Lord, who has believed our message
    and to whom has the arm of the Lord been revealed?”

39 For this reason they could not believe, because, as Isaiah says elsewhere:

40 “He has blinded their eyes
    and hardened their hearts,
so they can neither see with their eyes,
    nor understand with their hearts,
    nor turn—and I would heal them.”

41 Isaiah said this because he saw Jesus’ glory and spoke about him.

42 Yet at the same time many even among the leaders believed in him. But because of the Pharisees they would not openly acknowledge their faith for fear they would be put out of the synagogue; 43 for they loved human praise more than praise from God.

44 Then Jesus cried out, “Whoever believes in me does not believe in me only, but in the one who sent me. 45 The one who looks at me is seeing the one who sent me. 46 I have come into the world as a light, so that no one who believes in me should stay in darkness.

47 “If anyone hears my words but does not keep them, I do not judge that person. For I did not come to judge the world, but to save the world. 48 There is a judge for the one who rejects me and does not accept my words; the very words I have spoken will condemn them at the last day. 49 For I did not speak on my own, but the Father who sent me commanded me to say all that I have spoken. 50 I know that his command leads to eternal life. So whatever I say is just what the Father has told me to say.”

The Unbelief of the People

Observe the method of conversion implied here. Sinners are brought to see the reality of Divine things, and to have some knowledge of them. To be converted, and truly turned from sin to Christ, as their Happiness and Portion. God will heal them, will justify and sanctify them; will pardon their sins, which are as bleeding wounds, and mortify their corruptions, which are as lurking diseases. See the power of the world in smothering convictions, from regard to the applause or censure of men. Love of the praise of men, as a by-end in that which is good, will make a man a hypocrite when religion is in fashion, and credit is to be got by it; and love of the praise of men, as a base principle in that which is evil, will make a man an apostate, when religion is in disgrace, and credit is to be lost for it.

Our Lord publicly proclaimed, that every one who believed on him, as his true disciple, did not believe on him only, but on the Father who sent him. Beholding in Jesus the glory of the Father, we learn to obey, love, and trust in him. By daily looking to Him, who came a Light into the world, we are more and more freed from the darkness of ignorance, error, sin, and misery; we learn that the command of God our Saviour is everlasting life. But the same word will seal the condemnation of all who despise it, or neglect it.
