[Elsie]

In Jn 6:27 Jesus clearly said to WORK for the meat that endures unto everlasting life that the Son of man shall GIVE you.

Yes; it sure says that alright; but why have you apparently ignored what was said AFTER that?

Jesus gave them a work to do, the work of believing.

[Oneanddone]

The context of Jn 6:27-29 shows:

—that belief itself is a WORK

—one must WORK for everlasting life

So belief is a work one must do to have everlasting life which Christ GIVES for free. Even though everlasting life is a free gift it is NOT an unconditional gift. But comes with conditions and one must WORK to meet the conditions in order to receive the free gift of everlasting life.
