Why Is Doing Good Works Evidence of Salvation in the Tribulation Period, But Not Proof of Salvation Today?

Welcome to Grace in Focus radio. Today, Bob Wilkin and Leon Adkins are answering a question (based on Matthew 25) about the relation of works to salvation and whether works can ever evidence salvation. Does this happen during the Tribulation period, for example? Have there been different saving messages in different dispensations? Please listen for some Biblical clarity about this.
