What does the Bible say about being made new in Christ?

The concept of being made new in Christ is profoundly depicted in Revelation 21:5, where the one seated on the throne declares, 'Behold, I make all things new.' This promise signifies that for those who are in Christ, there is a complete transformation. The old self, marked by sin and its consequences, is replaced by a new identity that is completely cleansed and renewed. God, in His grace, removes the record of sin entirely, assuring believers that their past failures hold no claim over them (Jeremiah 50:20). This radical renewal is central to the gospel of grace.
