Last Sermon of Jesus
John 13:34-35 "A new commandment I give to you, that you love one another; as I have loved you, that you also love one another. By this all will know that you are My disciples, if you have love for one another."
Our Lord stated that when we love one another as He had loved us, then all (including Christians) will believe that we are truly His disciples (then there will be revival).
Acts 2:7-11 Then they were all amazed and marveled, saying to one another, "Look, are not all these who speak Galileans? And how is it that we hear, each in our own language in which we were born? Parthians and Medes and Elamites, those dwelling in Mesopotamia, Judea and Cappadocia, Pontus and Asia, Phrygia and Pamphylia, Egypt and the parts of Libya adjoining Cyrene, visitors from Rome, both Jews and proselytes, Cretans and Arabs—we hear them speaking in our own tongues the wonderful works of God."
The disciples saw the miracles that the Jews from the four corners of the earth heard the gospel in the dialects where they came from.
Acts 2:41-42,44-47 Then those who gladly received his word were baptized; and that day about three thousand souls were added to them. And they continued steadfastly in the apostles' doctrine and fellowship, in the breaking of bread, and in prayers. Now all who believed were together, and had all things in common, and sold their possessions and goods, and divided them among all, as anyone had need. So continuing daily with one accord in the temple, and breaking bread from house to house, they ate their food with gladness and simplicity of heart, praising God and having favor with all the people. And the Lord added to the church daily those who were being saved.
When the disciples saw that thousands were saved, they were filled with joy and they gave up everything they owned.
Acts 4:13-14 Now when they saw the boldness of Peter and John, and perceived that they were uneducated and untrained men, they marveled. And they realized that they had been with Jesus. And seeing the man who had been healed standing with them, they could say nothing against it.
Even the priesthood marvelled that these uneducated fishermen disciples of Jesus, were preaching fearlessly and also performing miracles.
Acts 4:32-35 Now the multitude of those who believed were of one heart and one soul; neither did anyone say that any of the things he possessed was his own, but they had all things in common. And with great power the apostles gave witness to the resurrection of the Lord Jesus. And great grace was upon them all. Nor was there anyone among them who lacked; for all who were possessors of lands or houses sold them, and brought the proceeds of the things that were sold, and laid them at the apostles' feet; and they distributed to each as anyone had need.
