Inclusivism is the doctrine that while no one can be saved apart from Christ, one need not have conscious faith in Christ to be saved.  So, for example, while a good Buddhist may not trust in Christ for his salvation, since he is a good Buddhist Christ applies the merits of His substitutionary atonement to him. 

The NT is opposed to inclusivism.  It is quite clear that one must exercise conscious faith in Christ to experience salvation: 

John 3:14-18  And as Moses lifted up the serpent in the wilderness, so must the Son of Man be lifted up, [15] that whoever believes in him may have eternal life. [16] “For God so loved the world, that he gave his only Son, that whoever believes in him should not perish but have eternal life. [17] For God did not send his Son into the world to condemn the world, but in order that the world might be saved through him. [18] Whoever believes in him is not condemned, but whoever does not believe is condemned already, because he has not believed in the name of the only Son of God.
