This commission given to disciples enabled them to share with others regardless of their culture, religious beliefs and backgrounds the good news of Jesus Christ. Today, however, this could easily be interpreted by many as a form of imposition of one faith upon another.
There is a difference between sharing and imposition. Sharing information is communicating or informing about something i.e. a subject or specific topic etc. Imposition is defined as to establish or apply as compulsory. Therefore it is understandable that when Christians communicate the Gospel and tell people that they have a choice of accepting Christ or going to hell which is an unpleasant truth it sounds like an imposition telling one what to do.
However, from the Christian point of view, this is a biblical truth - accept Christ as Saviour or be condemned eternally. I also think the reason people see this as an imposition is because deep down there is a slight fear of this unpleasant truth in that it might actually be true, but there is also an unwillingness to conform to Christianity. Therefore the easiest way seems to reject the whole concept of Salvation through Christ and blame the Christians for imposing their faith too harshly on others.
Even Jesus did say that the way of salvation is a hard and narrow way. So one can understand why it is difficult to accept Christ.
Britian today is seen as a multifaith society, which could be similar to the concept of religious pluralism. Religious pluralism is the belief that more than one religion can teach truths. In its strongest sense, religious pluralism holds that no religion can claim to teach the only or absolute truth. Religion is not literally the word of , but rather is mankind's attempt to describe the word of God. Given the finite and fallible nature of human beings, no religious text can absolutely describe God, or God's will, with absolute precision.
The Christian could argue according to Ephesians chapter 4 verses 4-6
‘ There is one body, and one spirit even as ye are called in one hope your calling; One Lord, one faith, one baptism, one God and father or all, who is above all, and through all, and in you all’. Based on this scripture, which is one of the founding pricipals of Christianity one can see how and why the Christian zeal for preaching the gospel and seeking to save the lost (lost according to the bible) will always be misinterepted as arrogant and aggressive.
In conclusion therefore I believe it is acceptable for Christians to keep preaching zealously because we believe that we are saving souls from eternal damnation as instructed by our Lord and saviour Jesus Christ. After all unfortunately, some Muslims are willing to kill for the purity of their faith.
