How will I get into heaven?

Not by any paperwork or evidences I can produce to prove my right, rather I will be recognized and know as belonging, thereby entering.

John 10:14 (KJV)

I am the good shepherd, and know my [sheep], and am known of mine.

John 10:7 (KJV)

Then said Jesus unto them again, Verily, verily, I say unto you, I am the door of the sheep.

John 3:16-20 (KJV) 16 For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life. 17 For God sent not his Son into the world to condemn the world; but that the world through him might be saved. 18 He that believeth on him is not condemned: but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God. 19 And this is the condemnation, that light is come into the world, and men loved darkness rather than light, because their deeds were evil. 20 For every one that doeth evil hateth the light, neither cometh to the light, lest his deeds should be reproved.

There is no other way. Only Jesus Christ. You cannot do it on your own. We all need help. And God sent us His help, His Son Jesus, to make the way. Take the gift of salvation offered by God in Christ Jesus and know eternal life :)
