What does Matthew 7:21-29 teach about salvation?

In this passage, Jesus provides a sobering reality about the nature of true salvation. He states that not everyone who calls Him 'Lord' will enter the kingdom of heaven, but only those who do the will of His Father. This emphasizes that merely professing faith or performing religious acts does not equate to true salvation. It is a call to self-examination, urging individuals to consider whether their faith is authentic, as true salvation produces a life that reflects obedience and relationship with Christ, who is our life and righteousness.
