Jesus came to the Earth once in the form of a human, He lived a perfect life and died and was resurrected... All with the intention and promise that He would come back a second time. The first Jesus came, He came to bring salvation and healing, at His second coming Jesus will come back for His children. We as believers will be taken up to be with Him in heaven for eternity. He's prepared a perfect place for each of us, there we will spend the rest of time singing praises to the Lord God Almighty.
