And Jesus came up and spoke to them, saying, "All authority has been given to Me in heaven and on earth. Go therefore and make disciples of all the nations, baptizing them in the name of the Father and the Son and the Holy Spirit, teaching them to observe all that I commanded you; and lo, I am with you always, even to the end of the age." Matthew 28:18-20
First the bad news.
Without a third party mediator between Earth and God, we are not able to go to Heaven. This applies to the entire human race. You are not alone.
We cannot be saved (get to heaven) just by being good. There is no amount of good things we can do to keep ourselves from being separated from God forever.
So, to be separated from God forever, simply do nothing. To ignore or reject God's son will keep us from going to Heaven, and the only other place you'll go is to Hell.
But there is good news!
There is a simple and free way to be accepted into heaven with God, made possible by God's only son Jesus. A blood sacrifice was needed to pay for your sins and Jesus was sent to become that sacrifice. He was nailed to a cross and shed His blood in payment for our sin. Then on the third day, He rose from the dead, having paid, once and for all, our debt and making it known that He is our Savior.
The one and only way God will allow us to reach Heaven, is by placing our complete trust in Jesus' death, burial, and resurrection.
This is a free gift from God because He loves us.
God so loved the world that He gave His only begotten Son, that whosoever believes in Him will not perish, but have eternal life!! (John 3:16)
