Are only Christians saved?
This topic has come up before and no doubt is one where not all Christians are agreed. 
The Bible doesn't say that only Christians will be saved. The term 'Christian' only appears 3 times in the Bible (Acts 11:26, Acts 26:28 and 1 Peter 4:16) and never in the context of delineating those who are saved.
The Bible does say that those who call upon the Lord will be saved (Romans 10:13), it says that those who feed the hungry (Matthew 25:31-46) and those who care as did the Good Samaritan (Luke 10:25-37) will be saved. 
It says that those born of the Spirit will be saved (John 3:3). It says that those who not only believe but do what the word says will be saved (James 2:24) and that not everyone who says 'Lord, Lord' will be saved (Matthew 7:21).
It says that there will be many sitting with Abraham in Christ's kingdom (Matthew 8:11) who we'll be surprised to see there. It even says God has concluded all humanity in unbelief that he might have mercy on us all (Romans 11:32)
All to say that God saves who He will save and as much as we want to draw the line on his behalf as to who is in and who is out, only He knows. (see John 21:21,22)
