Why is holding fast to Christ's name important?

In Revelation 2:13, Christ commends the church in Pergamos for holding fast to His name, which illustrates their commitment to His person and work amidst a culture of idolatry and persecution. This signifies that their identity and salvation are rooted in Christ alone, representing His authority, character, and the truth of the gospel they believe. Faithfulness to His name helps believers withstand trials and temptations, reinforcing their distinction from the world. It is crucial for Christians to maintain fidelity to Christ and not be ashamed of their relationship with Him, as this is what truly defines them as members of His church and possesses eternal significance.
