They received the power of the Holy Spirit, according to Christ's promise, and so they were his witnesses. (Acts 1.8)
But ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judaea, and in Samaria, and unto the uttermost part of the earth. (Acts 1.8)
They travelled across the nations, to preach the Gospel.
through the epistles
Our Lord Jesus Commissioned His Apostles to preach the Gospel. He Told them to go out & preach to all the Nations & Baptize then in the Name Of the Father, and Of the Son, and Of the Holy Spirit.
By my actions and deeds just as Jesus instructed his apostles. By sharing His Gospel. Visit mormon.org to find out what that is.
Matthew and Mark are the only 2 Apostles of Gospels.
The Apostles stressed that they must obey God rather than men and proclaimed the message of Jesus' resurrection before the religious council. They were bold in their faith and did not waver in their commitment to spreading the Gospel.
The Apostles began spreading the Gospel soon after Jesus' ascension in approximately 33AD.
To preach the Gospel.
I think more than two apostles were the founders of the early Christian churches. Jesus told all his disciples to take the Gospel message to other people in other cities and countries. When the apostles and disciples preached the Gospel and people believed then local churches were established. Peter is believed to have taken the gospel to Samaria, Joppa, Caesarea. Paul took the gospel to Antioch, Ephesus, Corinth and other places. Phillip the apostle is believed to have taken the gospel to parts of Asia Minor. John is believed to have gone with Phillip and Peter to parts of Samaria.
He accepted the Gospels and he used the Gospel in his favour.
Apostle literally means, one sent forth with a message. Jesus' 12 disciples, in Matthew 10 were sent forth by Jesus as apostles carrying the message of Jesus. For quite awhile they were the only apostles carrying this message, as the church was just beginning. Note that Jesus himself was also called an apostle, in Hebrews 3. He was "sent forth" by God, with a message and purpose.
St. Luke wrote two books in the New Testament: the Gospel of Luke and the Acts of the Apostles.
One responsibility of the apostles after Jesus' ascension was to spread his teachings and the gospel message to all nations, making disciples of all people. They were also called to baptize believers and continue the work that Jesus had started during his ministry.
There is no specific number, orignally there were 12 apostles; technically all Christians are called upon to be apostles of the gospel.
