What does the Bible say about doubting nothing?

In Acts 10:20, Peter receives a directive from the Lord to go to Cornelius, explicitly told to do so ‘doubting nothing.’ This phrase encapsulates the essence of a believer’s faith; it urges Christians to trust fully in God’s leading without reservations or fear. Doubts can easily creep in, especially when faced with challenges or contrary traditions, as seen in the Jewish context of Peter’s mission to the Gentiles. The message is clear: trusting God means stepping forward in faith, leaving behind uncertainties and embracing His call.
