How do we know the decrees in Acts 15 are still important today?

Acts 15 records the early church's decision that certain ethical standards, termed 'necessary things,' were to be observed by Gentile believers. These decrees included abstaining from idolatry, sexual immorality, consuming blood, and improperly slaughtered animals (Acts 15:28-29). The theological implications of these decrees emphasize that Christians are to maintain purity in both worship and lifestyle. The lasting significance is viewed in light of God's unchanging nature and the call to holiness among His people, making the decrees relevant not just in the first century but continuously necessary across the ages (1 Corinthians 1:10).
