We are multidimensional, eternal beings.
What dimension we live in - is up to us.
Ephesians 2:4-10
4 But God, who is rich in mercy, because of His great love with which He loved us,
5 even when we were dead in trespasses, made us alive together with Christ (by grace you have been saved),
6 (Boom!) and raised us up together, and made us sit together in the heavenly places in Christ Jesus,
7 that in the ages to come He might show the exceeding riches of His grace in His kindness toward us in Christ Jesus.
8 For by grace you have been saved through faith, and that not of yourselves; it is the gift of God,
9 not of works, lest anyone should boast.
10 For we are His workmanship, created in Christ Jesus for good works, which God prepared beforehand that we should walk in them.
