Why is Jacob's blessing of Ephraim and Manasseh important?

The blessing of Ephraim and Manasseh in Genesis 48 illustrates God's sovereign choice in the distribution of blessings. Jacob intentionally blesses Ephraim, the younger son, with the rights of the firstborn traditionally reserved for Manasseh. This act reinforces the biblical theme that God's purposes often overturn human conventions. It reflects the overarching narrative of grace in Scripture, where God's selection is based on His will, and it communicates the idea that many are called, but few are chosen for His special blessings.
