So if they believe in the same as you believe in, then (2:137)

﴿فَإِنْ آمَنُوا بِمِثْلِ مَا آمَنتُم بِهِ فَقَدِ اهْتَدَوا ۖ وَّإِن تَوَلَّوْا فَإِنَّمَا هُمْ فِي شِقَاقٍ ۖ فَسَيَكْفِيكَهُمُ اللَّهُ ۚ وَهُوَ السَّمِيعُ الْعَلِيمُ﴾
[ البقرة: 137]

2:137 So if they believe in the same as you believe in, then they have been [rightly] guided; but if they turn away, they are only in dissension, and Allah will be sufficient for you against them. And He is the Hearing, the Knowing.

If the Jews and the Christians, and other disbelievers, have faith in the same way that you do, then they have been guided to the right way of life which Allah is satisfied with.
Yet if they turn away from faith because they reject all the prophets or some of them, then they are in disagreement and are against you.
Do not be sad, O Prophet, because Allah will protect you from their harm and evil, and give you victory over them.
Allah hears all that they say, and knows all their intentions and actions.

So if they believe in the like of that which you believe, then they are rightly guided, but if they turn away, then they are only in opposition. So Allah will suffice you against them. And He is the All-Hearer, the All-Knower.
