You are the light of the world. A city that is set on a hill cannot be hidden. Nor do they light a lamp and put it under a basket, but on a lampstand, and it gives light to all who are in the house. Let your light so shine before men, that they may see your good works and glorify your Father in heaven.
In this parable, Jesus gives three servants an amount of money to use. While this “talent” is not the same as a musical talent, I think the fact that Jesus reprimanded and punished the servant that buried his money and never invested it could be applied to any ability a Christian has but does not use.
For everyone to whom much is given, from him much will be required; and to whom much has been committed, of him they will ask the more.
1 Peter 4:9-11
As each one has received a gift, minister it to one another, as good stewards of the manifold grace of God. If anyone speaks, let him speak as the oracles of God. If anyone ministers, let him do it as with the ability which God supplies, that in all things God may be glorified through Jesus Christ, to whom belong the glory and the dominion forever and ever. Amen.
