Jesus ’ disciples knew that they could not accomplish the preaching work on their own. Jesus had said that he would be with them and that the holy spirit would assist them.
لَا يُخْبِرُنَا ٱلْكِتَابُ ٱلْمُقَدَّسُ إِلَى أَيِّ حَدٍّ وَجَّهَ ٱللهُ ٱلْأَحْدَاثَ فِي ٱلْقَرْنِ ٱلْأَوَّلِ تَمْهِيدًا لِنَشْرِ ٱلْبِشَارَةِ .‏
