As you read the Acts of Apostles (the fifth book in the New Testament of the Bible) you get a clear picture of what was the heart of the earliest Christian preaching — the death, burial, and resurrection of Jesus.
This same gospel message is the heart of Christian belief today.
This message of love, sacrifice, and forgiveness is what should shape Chistian thought and behavior.
Check out the core message in the earliest Christian sermons.
“This man was handed over to you by God’s set purpose and foreknowledge; and you, with the help of wicked men, put him to death by nailing him to the cross. But God raised him from the dead, freeing him from the agony of death, because it was impossible for death to keep its hold on him.”
“You killed the author of life, but God raised him from the dead. We are witnesses of this.”
“Then Peter, filled with the Holy Spirit, said to them: ‘Rulers and elders of the people! If we are being called to account today for an act of kindness shown to a cripple and are asked how he was healed, then know this, you and all the people of Israel: It is by the name of Jesus Christ of Nazareth, whom you crucified but whom God raised from the dead, that this man stands before you healed.'”
“Peter and the other apostles replied: ‘We must obey God rather than men! The God of our fathers raised Jesus from the dead–whom you had killed by hanging him on a tree. God exalted him to his own right hand as Prince and Savior that he might give repentance and forgiveness of sins to Israel. We are witnesses of these things, and so is the Holy Spirit, whom God has given to those who obey him.'”
“You stiff-necked people, with uncircumcised hearts and ears! You are just like your fathers: You always resist the Holy Spirit! Was there ever a prophet your fathers did not persecute? They even killed those who predicted the coming of the Righteous One. And now you have betrayed and murdered him– you who have received the law that was put into effect through angels but have not obeyed it.”
“We are witnesses of everything he did in the country of the Jews and in Jerusalem. They killed him by hanging him on a tree, but God raised him from the dead on the third day and caused him to be seen.”
“Though they found no proper ground for a death sentence, they asked Pilate to have him executed. When they had carried out all that was written about him, they took him down from the tree and laid him in a tomb. But God raised him from the dead, and for many days he was seen by those who had traveled with him from Galilee to Jerusalem. They are now his witnesses to our people.”
“Therefore since we are God’s offspring, we should not think that the divine being is like gold or silver or stone–an image made by man’s design and skill. In the past God overlooked such ignorance, but now he commands all people everywhere to repent. For he has set a day when he will judge the world with justice by the man he has appointed. He has given proof of this to all men by raising him from the dead.”
