How do we know the relevance of the gospel across generations?

The relevance of the gospel across generations is grounded in its unchanging truth. As stated in Psalm 145, 'One generation shall praise thy works to another,' highlighting that the message of Christ and His redemptive work is the same for those who lived 2,000 years ago and those today. The gospel does not adapt to cultural shifts; instead, it transcends cultural differences, providing the same hope for all – that Christ is the only Savior. This consistency affirms that God's word is as powerful now as it was at its inception, equally addressing human sinfulness and need for salvation across all ages.
