"Do not let your hearts be troubled. You believe in God; believe also in me. My Father's house has many rooms; if that were not so, would I have told you that I am going there to prepare a place for you? And if I go and prepare a place for you, I will come back and take you to be with me that you also may be where I am."
John 14:1-3

There are few verses in Scripture that describe eternal life, but those few verses are rich with promises. Here Jesus says, "I am going to prepare a place for you" and "I will come back." We can look forward to eternal life because Jesus has promised it to all who believe in him. Although the details of eternity are unknown, we need not fear because Jesus is preparing for us and will spend eternity with us.
