The Lord Jesus told us whoever lives and believes in Him will never die. We understand He is not referring to physical death (which the New Testament often refers to as "sleep"). Somehow, it appears, the concept that the true saint will never die has been buried under the tradition of "going to Heaven."
Perhaps there is more to the idea of continuing to live than that of going to Heaven to reside forever. Perhaps the emphasis is on continuing to live on the earth. Maybe this is the meaning of John 3:16!
