Gen 42:1, When Jacob saw that there was grain in Egypt, Jacob said to his sons, “WHY DO YOU LOOK AT ONE ANOTHER?”
God was already working on their conscience by the mere mention of Egypt they remembered Joseph whom they sold even after 20 years!
Gen 42:20-21, AND BRING YOUR YOUNGEST BROTHER TO ME; SO YOUR WORDS WILL BE VERIFIED, and you shall not die.” And they did so. Then they said to one another, “WE ARE TRULY GUILTY CONCERNING OUR BROTHER, FOR WE SAW THE ANGUISH OF HIS SOUL WHEN HE PLEADED WITH US, AND WE WOULD NOT HEAR; therefore this distress has come upon us.”
Joseph tested his brothers to see if they had changed! Their guilty conscience finally spoke out saying “WE ARE TRULY GUILTY CONCERNING OUR BROTHER!” THEY REMEMBERED THE ANGUISH IN THEIR BROTHER JOSEPH, YET THEY WOULD NOT LISTEN!
JESUS CAME TO HIS BROTHERS (THE JEWS) AND THEY DIDN’T BELIEVE HIM NOR LISTEN TO HIM AND HIS BROTHERS SAW THE AGONY IN HIS FACE WHEN HE WAS CRUCIFIED ON THE CROSS!
Joh 1:11, HE CAME TO HIS OWN, AND HIS OWN DID NOT RECEIVE HIM.
OUR CONSCIENCE MAY CONDEMN US, BUT GOD USES IT TO RESTORE US BACK TO HIM!
