John 3:36 “He who believes in the Son has eternal life; but he who does not obey the Son will not see life, but the wrath of God abides on him.”
John 8:24 "I told you that you would die in your sins, for unless you believe that I am he you will die in your sins.” --'perish in your sins' is not a way of saying 'oh we all die anyways and then you'll get in-- in the context of John and the whole Bible it means you die under the penalty of sin and you perish eternally.

Update: Why in the world send workers into the field if everybody gets in already? If everybody is harvested, then we don't need workers. But if we take God's word seriously there are tares amongst the wheat and they will be burned with fire (e.g. judged and condemned) at the end of the age. See Matthew 13:36-43.
Harvesters are sent because people are lost and those who reject will be judged. For example see the context of Matthew 9 where in 10:6,14-15, 32-33.
Equally there is really no call for discipleship if we all get in anyone, or at least Jesus doesn't really mean what he says in 10:38-39. (unless you existentialize "he would has found his life will lose it").
