There IS something waiting for you after your physical death. The main event as it were to this life which, however short or long it lasts, is merely the prelude.
Where you end up (for eternity) is dependant on only one thing.
Did you believe on the Son of God Jesus Christ and accept Him as your personal saviour?
Jesus Christ is God. He has done everything possible for you to enter heaven, even giving His own precious Son to die on the cross for you. Especially you. All He asks is for you to come to Him, believe in Him, and receive Him. Salvation is a gift from God to all who ask for it.
Rest in Him and He will do the rest in you.
