When Jesus returns, every man will be rewarded for his works

But when the Son of man comes in his glory, and all the angels with him, then will he be seated in his glory: And before him all the nations will come together; and they will be parted one from another, as the sheep are parted from the goats by the keeper. And he will put the sheep on his right, but the goats on the left.
Matthew 25:31-33

To Believe In Jesus, Is To Do The Work Of God

Joh 6:29 Jesus answered and said unto them, This is the work of God, that ye believe on him whom he hath sent.
KJV

Earthly food spoils and ruins. So don’t work to get that kind of food. But work to get the food that stays good and gives you eternal life. Jesus will give you that food. Jesus is the only one qualified by God the Father to give it to you.”
The people asked Jesus, “What does God want us to do?
Jesus answered, “The work God wants you to do is this: to believe in the one he sent.”
