If you are called to function in the prophetic gift, will you continue to do this after you die? Will there be prophets in the new heaven and the new earth?
This is unlikely, for Paul says:
Love never fails. But where there are prophecies, they will cease; where there are tongues, they will be stilled; where there is knowledge, it will pass away. For we know in part and we prophesy in part, but when perfection comes, the imperfect disappears.
1 Corinthians 13:8-10
When we are born again, we receive a new identity as a son or daughter, a coheir with Jesus, a friend and a servant of our God. This multi faceted identity is eternal – we receive it in this world and it continues to the next.
However, many of the jobs we are asked to do in this world are temporary. They are important and necessary to build the Kingdom on earth. Yet when the building is finished, when the new heaven and earth are fully established, these jobs will no longer be needed.
In the time of Nehemiah, the perfume makers, the shepherds, the rulers, the guards, the servants, the goldsmiths and the priests all rebuilt the wall; yet once the wall was finished they returned to their land and their occupation to live.
The prophetic gift or office of the prophet is a necessary function to build the Kingdom here on earth; it is not who you are in Christ. If we embrace and hold on to our eternal identity in Christ we will be protected from defining ourselves by the temporary jobs we are given to outwork in this world.
To operate in the prophetic gift or to receive the office of a prophet is a task, a function that is given to administer in this life. It is not an identity that defines who you are, nor is it a role that will continue forever.
