God did not direct His call to Isaiah— Isaiah overheard God saying, “. . . who will go for Us?” The call of God is not just for a select few but for everyone. Whether I hear God’s call or not depends on the condition of my ears, and exactly what I hear depends upon my spiritual attitude. “Many are called, but few are chosen” (Matthew 22:14). That is, few prove that they are the chosen ones. The chosen ones are those who have come into a relationship with God through Jesus Christ and have had their spiritual condition changed and their ears opened.
