The question is not whether you exist eternally, but how that existence is experienced. Will you experience life, i.e. present with and useful to God; or death, i.e. absent from and useless to God (John 3:16). Your body and soul were designed to exist eternally. Your soul will immediately transfer to one of two realms, eternal torment separated from God or eternal life in His presence (Luke 16:22).
Life is experienced in the presence of God. The absence of life is the absence of God. John 3:36 tells us those who know the Savior (the Son) have life already. This life is a physical experience. Those who know the Son can live a viable life for God here on earth. As we work to accomplish His will in life on earth, we lay up our treasures in Heaven (Matthew 6:20). Any other work is laying up our treasures on earth where moth and dust corrupts (Matthew 6:19).
James 5:3 tells us about our works on earth without God. He says,
Your gold and silver is cankered; and the rust of them shall be a witness against you, and shall eat your flesh as it were fire. Ye have heaped treasure together for the last days.
Living here as though it were our last day every day can be beneficial if that life is a witness for Christ. However, if we concentrate on our bucket list, checking off our desired experiences we gain nothing, have accomplished nothing. Such a short sighted approach to life nets nothing. The more toys you gather, the less time you have to enjoy them Maintaining them eats up all your energy then makes you cynical about enjoying them (eat your flesh as it were fire).
Conversely, you can live a life full of Christ, in His service, for His glory, adding to His kingdom and have a life full of experiences and happiness. There will be trials, but they will grow you, strengthen and establish you. There will be suffering, but it will re-focus your life on Christ, bring you closer to Him, draw you to His presence. Life is lived here on earth, but the experiences of true living are born in a personal relationship with God through His Son.
