What does the Bible say about spiritual death and resurrection?

In Ephesians 2:1, Paul states that those who are outside of Christ are dead in their trespasses and sins. This spiritual death signifies a separation from God and an inability to respond to spiritual truths without divine intervention. However, the hope of resurrection is vividly presented in the Gospel, where Christ calls the dead to life. As illustrated in the account of Jairus's daughter, when Jesus states she is merely sleeping, he signifies that death for a believer is not the end but a temporary state before awakening to eternal life. The resurrection of believers at the last trumpet demonstrates God's ultimate triumph over death, affirming the assurance that they shall live again.
