Luke 6:30 Give to everyone who asks you, and if anyone takes what belongs to you, do not demand it back.
One of the ways we can show love toward others is by sharing with them; but love should go a lot further than just sharing things with people.
Anyone can share things; but not everyone is willing to share everything. God reminds us that we need to share willingly and freely without requiring payback for everything because that is not sharing.
God wants us to share His Gospel as freely as we would gifts we wanted to give away to make others happy. It is the gospel that people need; the truth.
