Judah became the leader of the family of Israel against the patriarchal order. He was not the oldest son and none had anointed him. He just grew into that position as a result of the quality of his heart.
Please read the whole history of the sons of Jacob. Joseph had taken Simeon as a hostage requiring that he should see also Benjamin in Egypt. Jacob had taken Benjamin as a substitute after having lost Joseph. The whole family was facing death by starvation unless the sons of Jacob would show up again before Joseph with Benjamin.
The oldest brother Reuben promised his two sons as a ransom, but this had no effect on Jacob's bitter and distressed heart. Then Judah made a proposal that totally changed the situation:
We can discern also other occasions, which prove that Judah had different kind of heart than his brothers. He did not commit to the idea of murdering Joseph. Instead, he made a wise proposal and prepared Joseph a way to survive. Judah was not with some of the brothers who destroyed Shechem. After falling in the sin with Tamar he confessed his sin and bore his responsibility of the act. Please note that in spite of his earlier weaknesses and failures Judah grew up in strength.
The commitment of Judah was painfully tested by Joseph. Judah had to tell Joseph the whole truth how he had given himself as a ransom for Benjamin. As a result of his commitment, he offered himself as a slave instead of Benjamin:
The words of Judah touched Joseph's heart deeply. He found that among his brothers there were now a man who was ready to offer his life for the benefit of the other! This was not the case when Joseph was thrown into the well to die. The unselfish love of Judah delivered Joseph's heart and Joseph was not anymore able to control himself and keep his secret!
Dear friend, this is the key of revival. When the heart of Judah is born in the church, then Jesus will be revealed. The enemy cannot anymore bind the hearts but the love of the Father starts flowing and healing people! When leaders of the church let their heart be transformed and start to give themselves as a ransom for the weaker ones then Jesus will manifest Himself in His power and glory. This change must come and it will come!
From this moment on Judah was the self-evident leader in the family. Please note how great a blessing Jacob released upon Judah. In his prophetic blessing Jacob foresees the coming of Jesus, the Lion of Judah!
When your heart is like Judah's heart, you will have true leadership in the Kingdom God. The anointing shall be your scepter and it shall not depart from you!
