Translations for 61:14 vary:
Muhammad Asad (The Message Of Quran)
61:14 O YOU who have attained to faith! Be helpers [in the cause of God - even as Jesus, the son of Mary, said unto the white-garbed ones,14 "Who will be my helpers in God's cause?" - whereupon the white-garbed [disciples] replied, "We shall be [thy] helpers [in the cause] of God!" And so [it happened that] some of the children of Israel came to believe [in the apostleship of Jesus], whereas others denied the truth.15 But [now] We have given strength against their foes unto those who have [truly] attained to faith:16 and they have become the ones that shall prevail.
So it could also be referring to the original followers of Jesus during his time. The reason why they will be superior is because Islam has come to make known that those people who truly followed Prophet Jesus peace be upon him are those who will be going to heaven and thus they are honored in this life.
May I ask why you are quoting from the Qur'an? This is a case for Paul's true apostleship which as a Muslim I imagine you don't accept. If you would like to have a discussion on Islam and Christianity me and Christian Anarchist are for that. But basically my question is, why is that relevant?
