Very few sermons close off as forcibly as the Sermon on the Mount. Jesus summons people to follow him, and the way he does this is to clarify the sort of followers he has in mind (beatitudes), the salt and light vocation, the surpassing righteousness he expects, and the simplicity of doing things with integrity and trusting God for provisions, and then a series of comments about discernment — and then Jesus simply calls people to follow.
Jesus is here not trying to frighten folks; he’s warning the arrogant possessors of gifts who think they’ve got a claim on God because of their service, their success, and their supernatural works. Jesus summons those who hear his words to follow him.
Giftedness does not equal redemption.
Allison suggests that what counts with Jesus is not supernatural giftedness but the gifts of charity and mercy and compassion — and there is good reason to think Matthew 25:31-46 can be brought into play here because it too is a judgment scene.
