We were buried therefore with him by baptism into death, in order that, just as Christ was raised from the dead by the glory of the Father, we too might walk in newness of life. - Romans 6:4
What sin do you struggle with? What is it that constantly defeats you? Whatever sin it is has been paid for and defeated on the cross by the blood of Jesus Christ. The victory is won, but you must truly strive for repentance, strive to kill the sinful desires of the flesh by and through faith in the person and work of Jesus Christ - there is no other way.
Imagine in a few years it is discovered that there is indeed a planet far far away inhabited by an alien race. This alien race is ahead of us technologically - but not by as much as we had for years speculated they would be. However, they are very advanced spiritually and emotionally. They never fight, argue, or even have disagreements. This race of aliens gets along great, and their planet is awesome because the planet actually is what to each alien mind feels and wishes it should be. It's everything the perfect planet could be for everyone there and even though they all have different tastes and interests all their tastes and interests are satisfied by the planets unfathomable ability to be the best it can be for each individual alien.
We earthlings send astronauts to investigate and the aliens on this planet treat our astronauts with grace and hospitality when they arrive. And after a very short time it becomes clear to the astronauts that this is the place that we humans need to move to - it is literally perfect. However, the aliens have one very strict law which states that the only way to become a citizen of their planet and live there is if you are born there. What a bummer.
So, as it is with us humans, we beg and plead and try our best to get the aliens to change the law - but they can't - it's not possible. We even try looking just like the aliens (they aren't little and grey with big eyes), we dress like them, learn to talk like them, walk like them, but it just can't be done. We cannot live on their planet.
So it is with the kingdom of heaven.
Put on all you like of Christianity, appear in every way Christian. However, if you are not born again of the spirit - then heaven is closed to you.
A person may do wonderful and caring works, spend their life in altruistic pursuits. If they are not born again of the spirit - then heaven is closed to them.
A reprobate in the clutches of the sins of alcoholism and addiction may strive valiantly and reform themselves. They may turn away from their destructive vices and lead a commendable life as a fine member of society. But if they are not born again of the spirit - then heaven is closed to them.
A christian is not a Christian without a Christian heart. And for a heart to be Christian it must be born again of the spirit in the heavenly country. To see and dwell in the kingdom of God we must be born anew there.
This may seem like a frightening and confrontational message - but it is the message the Lord gives us: "Truly, truly, I say to you, unless one is born of water and the Spirit, he cannot enter the kingdom of God." - Jesus (John 3:5)
There is no wiggle room.
Now I would remind you, brothers, of the gospel I preached to you, which you received, in which you stand, and by which you are being saved, if you hold fast to the word I preached to you—unless you believed in vain. For I delivered to you as of first importance what I also received: that Christ died for our sins in accordance with the Scriptures, that he was buried, that he was raised on the third day in accordance with the Scriptures, - 1 Corinthians 15:1-4
