What does it mean that Christ abolished death?

In 2 Timothy 1:10, it states that Christ abolished death and brought life and immortality to light through the gospel. This means that by taking on the sins of humanity and dying on the cross, Jesus conquered the power of death. He bore our deadness—spiritual and physical—and transformed it through His resurrection. The victory over death is extended to all who believe in Him, as His resurrection serves as a guarantee that believers will also be raised to everlasting life. Thus, death is no longer a source of fear for Christians, but rather a passageway to the ultimate fulfillment of life in Christ.
