Our imperfect flesh can weaken our resolve to stay alert. Jesus knew of the tendency that imperfect humans have to succumb to the weaknesses of the flesh. Consider what happened the night before Jesus was to be executed.
١٥ مَاذَا حَدَثَ لِبُطْرُسَ وَيَعْقُوبَ وَيُوحَنَّا ،‏ وَكَيْفَ يُمْكِنُ أَنْ يَحْدُثَ لَنَا ٱلْأَمْرُ عَيْنُهُ ؟‏
