The bible tells us that they is some humans in heaven already. We must know that those who died believing in God will always go back to God after death.
The account of the rich man and Lazarus also describes a contrast after death, where the righteous are comforted, suggesting a real experience of peace in God’s presence.
At the same time, Scripture points forward to a future resurrection when believers will receive glorified bodies. While the soul may be with God now, the fullness of life in heaven will be completed at the resurrection when Christ returns.
This means that, according to the Bible, there are humans in heaven now in spirit, rejoicing with God, while they await the final restoration of all things.
