Why is there so many different reasons for the spread of christianity?
Christianity is a gift from heaven, only the chosen ones receive it apparently the people at the time of the early spread of Christianity believed in God and his promise to their ancestors and were expecting the Messiah that why they believed and Christianity spread. moreover the disciples believed in Jesus and received Him in their lives and so God enabled them to perform miracles in His name which made people see God’s power and deepen their faith. God still enable us to perform miracles these days but only if we believe in him and receive Jesus as our Saviour.
