God does not have to do anything for us - Everything He does is by grace
Dr. Roberto Miranda(Audio: Spanish)
The Lord speaks of a servant who has spent the whole day working, he arrives at his master's house in the afternoon or at night, and this Lord instead of saying to him: hey come in, rest, make yourself comfortable, he orders him Let him continue working, and the Lord Jesus Christ says: This is the way men normally deal with their servants. And He says: You are also servants, and when you have done all that God hope you have done, you must say to yourselves: we are useless servants because we did everything we were asked to do.
And in our last meditation I said that the Lord is using this parable of a servant mistreated by his master as a hyperbolic, exaggerated illustration of a very important truth that we always have to take into account in our relationship with God and that is the The basis of any proper relationship of a child of God with the Creator God, the most high, almighty God, and that attitude of recognition of our smallness before the greatness of God must be the foundation of all the things that we do here on Earth.
