Here is a third lesson about watchfulness that we can learn from the apostles: They kept on bearing thorough witness despite obstacles. Preaching with zeal and urgency is vital to keeping on the watch.
وَرَغْمَ أَنَّهُ ٱحْتَمَلَ مَشَقَّاتٍ عَدِيدَةً ،‏ لَمْ تَفْتُرْ غَيْرَتُهُ أَوْ يَخِفَّ شُعُورُهُ بِٱلْإِلْحَاحِ قَطُّ .‏ —‏ ٢ كو ١١ :‏ ​ ٢٣ -‏ ٢٩‏ .‏
