Am I not allowed to do what I choose with what belongs to me? Or do you begrudge my generosity?

Matthew 20:15 (ESV)

Jesus regularly uses parables to illustrate the nature and meaning of the Kingdom of God. In the parable of the workers, a wealthy landowner who hires workers to work for him at different hours of the day. At the end, everyone gets paid the same for their labour. However, the workers who had worked all day felt that this was unfair and denounced the landowner’s generosity as injustice.

The economy of the Kingdom is different from the economy of the world. God is just as generous as the landowner, and how much He blesses us doesn't have anything to do with how much we labour for Him. It is not based on merit but on grace. What the parable doesn't teach is that we should be lazy and not doing anything; after all, God will continue to bless us. This is where a lot of people misunderstand the gospel of grace.

God is not only just but also merciful.

He does not give us what we deserve, but what we need.

All of us are guilty of sin before God, but some sins are worse than others in terms of how they violate God's concern for our responsibility towards others. Even though our Father's favour may be extended disproportionately to those who appear to be least worthy, no one can accuse Him of giving less than what He has promised. This is why we should be thankful to God for our salvation. It is an absolutely free gift of grace from God, which no one can earn, let alone demand.

When we experience God’s generosity, we become generous ourselves, and be a blessing to others in the same way we have been blessed. Grace will never cause you to hold back from God or others. Rather, grace should make you just and righteous in all that you do.
