During the three and a half years of Jesus’ public life ministry, many people believed in Jesus and followed Him. However, they did not really believe in Jesus as the Christ. As a result, when Jesus was crucified to death, all those who followed Jesus, including his disciples, fled leaving Jesus behind.
Mark 14:50 And they all forsook him, and fled.
According to the Bible’s prophecy that Jesus died on the cross and Christ was resurrected, only after He was resurrected on the third day, the disciples would truly believe that Jesus is the Christ and that the Old Testament and Jesus’ words for three and a half years were accurately understood to them.
John 2:22 When therefore he was risen from the dead, his disciples remembered that he had said this unto them; and they believed the scripture, and the word which Jesus had said.
What happened to the early church members after they came to believe that Jesus is the Christ? They are compelled to preach that Jesus is the Christ. The members of the early church continued to teach that Jesus is the Christ, whether they were gathered in the temple or at home, and from outside they told unbelievers that Jesus is the Christ.
Acts 5:42 And daily in the temple, and in every house, they ceased not to teach and preach Jesus Christ.
Through his sermons, Peter proved that the Christ whom he said would come from the Old Testament was Jesus, and many people believed this and the number of saints increased dramatically.
Acts 2:36 Therefore let all the house of Israel know assuredly, that God hath made the same Jesus, whom ye have crucified, both Lord and Christ. 37 Now when they heard this, they were pricked in their heart, and said unto Peter and to the rest of the apostles, Men and brethren, what shall we do? 38 Then Peter said unto them, Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost. 39 For the promise is unto you, and to your children, and to all that are afar off, even as many as the Lord our God shall call. 40 And with many other words did he testify and exhort, saying, Save yourselves from this untoward generation. 41 Then they that gladly received his word were baptized: and the same day there were added unto them about three thousand souls.
The resurrected Jesus also commanded the disciples and the believers who believe in Jesus to go to all nations to preach that Jesus is the Christ and to baptize those who believe.
Mt 28:19 Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost: 20 Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you always, even unto the end of the world. Amen.
Mk 16:15 And he said unto them, Go ye into all the world, and preach the gospel to every creature.
When we believe in Jesus as the Christ, the Holy Spirit of God that came upon us also guides and works to convey us to the world that Jesus is the Christ.
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.
When we believe in Jesus as the Christ, the Holy Spirit of God that came upon us also guides and works to convey us to the world that Jesus is the Christ.
Acts 4:20 For we cannot but speak the things which we have seen and heard.
Acts 5:42 And daily in the temple, and in every house, they ceased not to teach and preach Jesus Christ.
In conclusion, if we truly believe that Jesus is the Christ, we will give our whole life to preach this gospel of Jesus as the Christ to the world.
