The same principle applies to our relationship with God. Yes, we need to make the "connection" in order to gain access to the knowledge God wanted us to have. And yes, it would be a total advantage to "know" someone to get our foot in the door. And that person would be Jesus. So simply put the connection to God and heaven is through our savior Jesus Christ. Knowing that will pay big dividends during our lifetime and beyond.
... but in these last days he has spoken to us by his Son, whom he appointed the heir of all things, through whom also he created the world. He is the radiance of the glory of God and the exact imprint of his nature, and he upholds the universe by the word of his power.
