4. Preaching the gospel of love:
The ministry of the first preachers started in evil world, filled with darkness, characterized with selfishness, and separated with wars, and invasions. Christianity called for love for all, even enemies, as its slogan. It teaches that love is “the first and great commandment” (Matt22:38), it is “the purpose of the commandment” (1Tim1:5), and it is sign of the true discipleship to the Lord “By this all will know that you are My disciples, if you have love for one another” (Jhn13:35). More than that, it evaluated love and elevated its value as it taught that “God is love” (1Jhn4:8). It also taught that any virtue free from love is unacceptable, even if its gainer has faith to move mountains and speaks with the tongues of angels (1Cor13). Christian teaching to love the enemies was something new to hear at the ancient world; about which no thinker or philosopher thought. Christianity aimed to convert hating people into loving brothers “Therefore if your enemy hungers, feed him; If he thirsts, give him a drink; For in so doing you will heap coals of fire on his head. Do not be overcome by evil, but overcome evil with good” (Rom12:20, 21). Love was not just a sweat words uttered by the first preachers, but it was lived by them and obvious in their deeds.

5. The ministry was supported with the methods of grace:
We shouldn’t neglect a great secret for the growing ministry; which encouraged and supported it, i.e. prayer and fasting. From the early beginning, we know that the members of the early church were “continued with one accord in prayer and supplication” (Act1:14). These prayers were strong, acceptable and capable to shake the buildings (Act4:31). The early church used to pray for solving all their problems. That is obvious in the book of Acts (Act4:23-31; Act12). These prayers were usually accompanied by fasting (Act13:2,3; 14:23)… and the result was “the word of God spread, and the number of the disciples multiplied greatly in Jerusalem, and a great many of the priests were obedient to the faith” (Act6:7)… and “The churches were strengthened in the faith, and increased in number daily” (Act16:4)… and “The word of the Lord grew mightily and prevailed” (Act19:20).
