We are all made to worship through the talents that God has provided us with. We mostly think of worshipping in the church through song or in a band, but we can worship in any setting. For piano players, that is by playing piano and praising Him that way. Worship is the way we can thank Him for everything He has done for us, and piano players are able to do so through playing the musical instrument.
Psalm 100: 2 states: “Worship the Lord with gladness; come before him with joyful songs.” This design is perfect to let everyone else know that you are made to worship.
