"Well done, good and faithful servant" are words of praise found in the Bible that every believer should want to hear when they meet Jesus face to face for the first time. However, a lot more goes into making it possible to hear these words from Jesus than most believers know and understand.
God's grace saves us through faith in Jesus, yes, but God's Word also says we are 'scarcely' saved through our faith (1 Peter 4:18). So, it would make sense that to hear "Well done, good and faithful servant," would be dependent upon other things that go along with our faith, that will determine whether or not we will hear those words when we stand and kneel before our Lord and Savior Jesus Christ.
This book, Well Done, Good and Faithful Servant: How to hear those words when you meet Jesus face to face, was written to help you know and understand what those things are, all according to God's Word.
