A landowner hires laborers at different hours and pays everyone the same denarius, starting with the last. Those hired first grumble, and he answers that he has done them no wrong: is their eye envious because he is generous? The lesson calls that grumbling a serious accusation against God’s graciousness. The fault lies not with God but with man’s false idea of justice.
The slides set out God’s testimony about man’s true condition: dead in sin, by nature children of wrath, suppressing the truth, without hope and without God. They then take up the question “How can a loving God send people to hell?” The problem is not God’s badness but that He is good, just and holy, while sinners store up wrath by unrepentant hearts. Yet God has provided an escape in His Son. The last shall be first, and salvation is given freely and equally to all who come to faith in Jesus.
