God's invitation to 'come' in Genesis 7 reveals the essence of salvation - it always begins with God's initiative, not our merit. The ark serves as a powerful picture of Christ, offering refuge from judgment through simple faith. This divine call extends to families, emphasizing parents' responsibility to create gospel-centered homes. True salvation naturally leads to worship in every aspect of life, while God's patience in judgment demonstrates both His mercy and the urgency of responding to His call. Noah's immediate obedience reminds us that authentic faith always manifests in action - not just in dramatic moments, but in daily, disciplined obedience.
