Only by giving through cost to self will it leave a great big impact.
For we want them to see Christ who  giving to them through us.
Yes we can give without any cost to ourselves, to reach out to others.
But when it does cost us, then the lost will see even greater love in us.
True even giving a little will be glorified by our Living Savior God.
But imagine this, leaving a great impact in their lives that shall change them.
Revealing to them Christ heart within us thus bringing them into a life, of both hope and change within them through the giving that did cost us as well.
