I am not of the cessationist school and affirm the gifts of the Spirit as valid today. Thus, I have not considered the office of prophet in the present tense, even when reading this statement by the Westminster Divines previously. I believe the last true prophet passed from this temporal world by the end of the first century. While I wouldn't plant my feet in concrete, I don't think the office of prophet as we can understand it as men, nor point to it in biblical history is being presently exercised by Christ. We see him fill this office perfectly in His earthly ministry as the God-man, Jesus Christ.
Intercession can rightly belong to both offices.
We then are left with the question of the present tense in Christ as prophet. I choose to think His role as prophet has ended. His word, being the Holy Scriptures, we indeed have in the present tense. Nonetheless, none can understand these apart from the illumination of the Holy Spirit, and my thoughts return to the beginning. In the true sense of the word prophet in Scripture, none exist today, to include Jesus Christ.
