You cannot multiply what you do not sow
We are still talking about necessity to use the gifts that have been given to us by the Lord. Jesus wants every person to be faithful in little things and then God will place such a person over greater things. God presents everyone with opportunities to start serving Him and bringing forth fruit for God’s Kingdom. You cannot multiply what you do not sow.
In the Gospel of Mathew Jesus told a parable about Master giving his servants different talents.
