Paradise is also referred to as Abraham's Bosom. Before Jesus Christ died on the cross, there was a place called Sheol, with two distinct areas.
There is a place where the damned still await their final judgement, and the other called Abraham's Bosom (Paradise) where the Old Testament saints went who were not to be damned, but were waiting for Jesus Christ’s resurrection.
Many of the saints who died and were in the earth were seen risen and walking around on the surface of the earth after Jesus Christ rose from the dead. The saints were atoned for went with Jesus Christ into heaven and will return with Him at His second coming.
Abraham’s Bosom (Paradise) is now an empty place in the earth.
