This definition can be seen in the Parable of the Wedding Banquet (Matt 22:1-14)
where Jesus uses the Greek verb for call, "kaleō," with a meaning of "invite" five times.
People, regardless of qualification, were invited as guests to the wedding banquet of the king's son.
Those who came had to have the proper wedding garments (Isa 61:10).
Without one, the guest was thrown out "into the outer darkness" where "there will be weeping and gnashing of teeth."
The parable ends with "many are called, but few are chosen" which indicates that those "called" are not necessarily "chosen." The
invited have the choice to come freely or not as holy people; but, if they come, they must put on the proper clothing symbolic of faith in
Jesus. Those who believe are of the "elect." This becomes literally true at the end of human history
