John 6:37

These people’s lack of faith did not indicate that Jesus or God’s plan had failed, however. The ability to believe on Jesus requires divine enablement. It is only those whom the Father enables to believe that come to Jesus in faith. These are the people whom the Father has given to the Son as gifts. Jesus viewed the ultimate cause of faith as God’s electing grace, not man’s choice.

Jesus promised not to turn away anyone who came to Him in faith. He used a figure of speech (litotes) to stress strongly the positive fact that all who believe in Him find acceptance and security. In litotes the speaker or writer affirms a positive truth by negating its opposite. For example, "This is no small matter," is a litotes meaning, "This is a very significant matter." In the first part of this verse Jesus spoke of the elect as a group, and in the second part He referred to every individual in the group. Jesus had confidence in the Father drawing the elect to Him, and the believer may have confidence too in the Son receiving and retaining him or her. How can a person know if he or she is one of the elect? Let him or her come to Jesus in faith.
