This sermon unpacks the Parable of the Workers in the Vineyard (Matthew 20:1-16) as a profound revelation of God's sovereign grace, challenging human notions of fairness and merit. Centered on the master's generous payment of a full day's wage to all workers regardless of when they began, the parable exposes the danger of spiritual entitlement and the human tendency to measure divine justice by personal effort and expectation. The preacher illustrates how the apostles, like modern believers, often approach God with a mindset of earned reward, only to find that the kingdom operates on grace, not merit—where the last are made first and the first last. The message is a sobering call to rejoice in God's generosity, even when it defies our sense of fairness, and to abandon any spiritual ledger of deserved reward in favor of humble gratitude for unmerited favor. Ultimately, the parable reveals that eternal life is not a wage earned by labor but a gift freely given by a merciful God, who calls all into His vineyard and crowns them equally with grace.
