The call of God is for everyone, scripture reads, "for many are called, but few are chosen" Matt 22:14 KJV. However the few that are chosen, have come into

relationship with God, and are able to hear his voice.  Because they are chosen they respond to the will of God.  For example, the Prophet Isaiah heard, the

call of the Lord, "who will go for us, his response here am I, send me.  God did not force His will on Isaiah, because the Prophet Isaiah was in God's presence

he was able to hear the call and respond.  Don't expect God to force you or plead with you to respond to His call.  The Prophet Isaiah in "perfect liberty said

"here am I send Me' !  How will you respond to the call of the Lord today ?
