Luke 24.
Perhaps you will read it today. 

Particularly verses 44 through 49.

⁴⁴ Yeshua said to them, “This is what I meant when I was still with you and told you that everything written about me in the Torah of Moshe, the Prophets and the Psalms had to be fulfilled.”
⁴⁵ Then he opened their minds, so that they could understand the Tanakh,
⁴⁶ telling them, “Here is what it says: the Messiah is to suffer and to rise from the dead on the third day;
⁴⁷ and in his name repentance leading to forgiveness of sins is to be proclaimed to people from all nations, starting with Yerushalayim.
⁴⁸ You are witnesses of these things.
⁴⁹ Now I am sending forth upon you what my Father promised, so stay here in the city until you have been equipped with power from above.”  source

Then He opened their minds, so that they could understand the Tanakh. 
Some Texts read so that they could understand the Scriptures. 

The Tanakh is Scripture. 

Of all the things to which we need our minds opened is Scripture, so we can understand. 
Yeshua did this for His Disciples and The Comforter, The Teacher He sent – Holy Spirit – still does this today for us, who are His Disciples. 
Aren’t you glad? 

One more thing. Don’t miss this: repentance leading to forgiveness of sins is to be proclaimed to people from all nations.

People NEED repentance leading to forgiveness of sins – but how will they hear, if we do not tell them? 
Shall we?
