Jesus answers this question in a conversation with some Pharisees in Luke 11. After condeming them for their self-righteous, external only, judgmental religion, Jesus said Luke 11:41 “but rather give alms of such things as you have; then indeed all things are clean to you.
Note two points in His reply:
1. As always, giving is from “of such things as you have”. If we can’t give because we don’t have, God doesn’t expect it of us.
2. Giving alms (with the right attitude of course) it is an indication of how true, pure, and clean our heart is before God. Note how Jesus puts it – he doesn’t just say “then all things are clean to you”, but “then INDEED…”.
This passage along with 1 John 3:16-19 (it says the same) tells us that a willingness to share is a very strong confirmation that we have the kind of pure heart we ought to have.
Question: Why is sharing our physical goods with the poor a true indication of a genuine pure heart?
