“All that the Father gives Me will come to Me, and the one who comes to Me I will certainly not cast out.”  (John 6:37)

The verbal sparring that Jesus engaged in often through the book of John is with the religious leaders who assumed that they were in God’s favor and had been so for quite some time.  Jesus continually made the point that the ones who were in God’s favor were the ones whom God drew to Himself and those He drew were the ones who recognized Jesus as the Savior.   This was the problem, really.  If they did not recognize Jesus as the Bread of Life, then that showed that they were on the outside, not the inside as they had assumed.  The opposite is true as well.  Those who recognized Jesus as the Son of God He was, was given to Jesus from the Father.  And they must never fear that Jesus would cast them out.
