Paul begins his letter by establishing his identity as an apostle, a role he holds not by personal ambition but by the will of God. This introduction is significant as it underscores the divine authority and purpose behind his message. Addressing the believers in Ephesus, Paul refers to them as 'God’s holy people' and 'faithful in Christ Jesus,' highlighting their sanctified status and commitment to their faith. This greeting not only acknowledges their spiritual identity but also serves as an encouragement to continue living in accordance with their calling.
The use of 'holy' signifies that the believers are set apart for God's purposes, while 'faithful' reflects their steadfastness in following Christ. By addressing them in this manner, Paul reminds the Ephesians of their unique relationship with God and the responsibilities that come with it. This opening verse sets a foundation for the themes of unity, identity, and purpose that Paul will explore throughout the letter, encouraging Christians to embrace their role as part of God's family and live out their faith with dedication.
