Faith is what is needed to be saved: as Paul and Silas testify in Acts 16, “Believe in the Lord Jesus, and you will be saved—you and your household.” Good works can never make us right with God – because we are inherently sinful, nothing we do is pleasing to God without His help.
“For God so loved the world, that he gave his only Son, that whoever believes in him should not perish but have eternal life.” John 3:16
