Yet I also believe God so loved the world that He gave His only begotten Son, so that whosoever believes in Him should not perish but have everlasting life (John 3:16). Those who believe in Jesus as Lord of their lives, inherit eternal bliss – in three (triune) stages.
First, they receive Christ here and now – and thereby enter into the Kindom of Heaven here on Earth (John 5:24). Second, when they die, their souls go to Heaven – where they enjoy conscious bliss with Jesus until His second coming (Rev. 4:1-11). And third, with Christ's second coming back to this Earth to transform it, He brings Heaven and its inhabitants with Him – so that Heaven then comes down to Earth (Rev. 21:1-2). Then the saved will get back their immortalized bodies, and thenceforth perfectly love God and enjoy Him forever in both soul and body (I Cor. 15:35-58). See here the Catechism, Q. 1.
