The purpose of this study is to educate fellow Christians all over the world about the positive and negative impacts globalisation has on Christianity and our Christian lives. It is also to enlighten us that globalisation is not evil, and it is not a human idea but God’s idea to fulfil His purpose of saving the estranged world—the lost souls. This is principally so when He said at the beginning of creation that man should be fruitful, multiplied, and replenished the earth. This was validated by our Lord Jesus Christ when He commanded His disciples to globalise the good news for the entire world. The cerebral missionary giant, Paul, the Apostle, cashed in on Jesus’ command by globalising Christianity through his missionary journeys in major cities of the ancient world before the invention of technology. This is globalisation in its embryonic stage. This paper employed secondary sources of data collection. It used a comparative method but was descriptive and analytical in nature. It also adopted the cause-effects theory, which discusses the impact of social systems as a result of their causes, and the selective acceptance theory to cushion the negative effects of globalisation on Christianity or completely eradicate them. The study redefines globalisation and traces its etymology to God to set the record straight. It also attempts an analysis of the interplay between Christianity and globalisation. The paper makes some recommendations and concludes that globalisation is God’s fulfilment of the great promise to save the entire human race.
