Why should Christians trust in the gospel's power?

Christians trust in the power of the gospel because it is rooted in God's sovereign design for salvation. The declaration of the gospel is not about human effort but is a means by which God actively draws His chosen ones to Himself. Romans 1:16 affirms that the gospel is the power of God for salvation to everyone who believes. In the context of the Israelite march around Jericho, their simple act of obedience to proclaim the gospel through their actions mirrors how Christians are called to declare the truth of Christ. The effectiveness of the gospel lies in God's authority, which is why believers can confidently share it, knowing it has the power to bring about transformation and salvation (1 Corinthians 1:21).
