His saying: "And we have come to know" means: we have realized "that we will never escape Allah," that is: we will not outstrip Allah such that He is unable to reach us, so He will resurrect us on the Day of Resurrection.
قَوْله: ﴿وَأَنا ظننا﴾ عَلِمْنَا ﴿أَنْ لَنْ نُعْجِزَ اللَّهَ﴾ أَنْ نَسْبِقَ اللَّهَ حَتَّى لَا يَقْدِرُ عَلَيْنَا؛ فَيَبْعَثَنَا يَوْمَ الْقِيَامَةِ.
