How do we know that humility leads to salvation?

In the text, humility is portrayed as essential to receiving God's grace and consequently salvation. Those who approach God with a humble heart recognize their inability to save themselves and their need for Christ's righteousness. This is illustrated in the parable of the wedding feast, where Jesus instructs those invited to take the lowest seat, symbolizing an acceptance of their spiritual condition. This principle is echoed throughout Scripture, where the humble are promised favor by God, resulting in salvation provided through Christ alone, ultimately leading to eternal life and communion with Him.
