The disciples of Jesus were concerned about their reward for being with and following Jesus. In the Gospel reading Jesus reminds them that they are merely servants of God, expected to serve as told. Indeed our everything has been given to us by God from his limitless love and generosity to share his happiness with us. We really do not deserve anything from God: everything is a gift from him: we cannot make demands from God.
In the first reading we are told that those who are faithful to God are assured of their reward from God.
The saints lived like this: they always thought themselves as worthless servants before the Lord. They served because they loved and were grateful to the Lord. They realized their sinfulness before God and were ever grateful to God for his merciful love for them.
Let us pray for similar understanding and wisdom to realize that, before God, we are worthless servants, but servants blessed and loved by God. As Mary prayed in her Magnificat: “My soul proclaims the greatness of the Lord; my spirit exults in God my savior! He has looked upon his servant in her lowliness, and people forever will call me blessed. The Mighty One has done great things for me, holy is his Name.”
