Why do so many people believe in the resurrection but never experience its power?
Many people mentally assent to the resurrection, speak and sing about it, yet never personally believe the Gospel or apply Christ's finished work to themselves. The resurrection's power becomes experiential only when a person trusts that Christ died and rose for them, paying the sin debt personally, rather than merely acknowledging it outwardly.
In the transcript, Les explains that this is where so many people are: they talk about the resurrection, they sing about it, and they have a mental ascent to it, but they have never really experienced resurrection power in their own life. Paul is trying to teach that the heart of the Gospel is not merely that Christ died a martyr's death or was put to death by an angry mob. In the annals of all eternity, God had already set it in motion that He would die, shed His blood, and pay the sin debt for the whole human race, not just for the believer. Les says he does not believe in limited atonement; he believes Christ paid the sin debt for every human being that has ever lived. But that payment goes for nothing until the person believes it personally, and then they cash in. So the resurrection is more than a fact to acknowledge; its power is realized when the individual personally trusts the Gospel.
