Warren:
I agree with Chrys in regards to other faiths as religion is only manmade philosophy. True Christianity is a relationship, a personal relationship with Jesus Christ as Lord, Savior, King, Creator, and our dearest and best friend.
I personally view people outside the true Christian faith as a mission field to whom we are to preach the gospel and make disciples in obedience to Christ's direct instructions. (Matthew 28:19-20, Mark 16:15-18)
