These texts should give you a very clear answer styley, and leave you under no illusion about who and who does not enter heaven. It's too serious a subject for sitting on the fence, trying to be all things to all men when your eternal life is at stake.
John's Gospel, if you can get hold of a modern version is the one to read.
John 3.16. "For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life".
John 3.17.�For God did not send his Son into the world to condemn the world, but to save the world through him�.
John 3.18. " Whoever believes in him is not condemned, but whoever does not believe stands condemned already because he has not believed in the name of God's one and only Son".
John 3. 36. " Whoever believes in the Son has eternal life, but whoever rejects the Son will not see life, for God's wrath remains on him".
It cannot be any plainer, can it? If you reject God or are anti Jesus, or worse - pour scorn and abuse on his name or his followers in this life, then you obviously will not want him when you are dead and all the good deeds in the world will not get you there.
God in his love and mercy wants everyone to be in heaven, but it�s plain that not everyone will accept this wonderful free gift.
