How do we know the gospel is always a triumph?

The gospel message is described as the aroma of Christ; it is guaranteed to bear fruit according to God's sovereign will. Romans 1:16 states that the gospel is the power of God for salvation to everyone who believes. Therefore, every time the true gospel is preached, it accomplishes God's purpose, whether the listener accepts or rejects it. The gospel's efficacy is not dependent on human response but on God's sovereign design, ensuring that it triumphs in the hearts of believers and is a sweet savor unto God.
