Matthew 28:18 And Jesus came and spoke to them, saying, "All authority has been given to Me in heaven and on earth. 19 Go therefore F166 and make disciples of all the nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, 20 teaching them to observe all things that I have commanded you; and lo, I am with you always, even to the end of the age." Amen.
To have a meaningful conversation about this, it can only be a dialogue. As long as one person believes he has the Truth and the person he is speaking to is lost, nothing is achieved.
It seems to be a quality of some religions to do this. Others, such as Hinduism or Taoism perhaps, seem not to care at all if anyone comes along with them.
Personally, I respect that.
