What does heavenly treasure have to do with anxiety?When we look at the parallel passage in Luke and other materials from the time of Jesus, we see that storing up treasures in heaven was the same as showing charity to the poor and the needy.
Jesus warned His disciples not to practice their spirituality in order to be admired by people. It’s pride that leads us to demonstrate our charity, prayer, and fasting to people rather than God. God looks down on such religion. It fails to meet His approval. But, when we do things for His eyes only, He not only approves our actions but also blesses us before all.
