What does the Bible say about not being ashamed of the Gospel?

In 2 Timothy 1:8-12, the Apostle Paul emphasizes the importance of not being ashamed of the testimony of Christ. He encourages Timothy to participate in the sufferings for the Gospel according to the power of God, underscoring that salvation is not according to our works but according to God's purpose and grace. The Gospel is a source of comfort and strength, and Paul himself was proud to suffer for the Gospel, knowing that God is powerful to guard what has been entrusted to him until that day. This assurance transforms the perception of suffering and shame into a badge of honor for believers.
