I love this thought from E. Stanley Jones, “We must not be self-contained, we must be Christ-contained. We must depend on Him for our primary refreshment. Then if anything comes from without it is all something thrown in, a plus. Glance at the refreshments from without, gaze at the refreshment in Christ. We must give refreshment to others if we are to keep it in Him.”
Everyone is not in the same place in their relationship with the Lord as you are. To many, what you receive from Him is the only contact they will have today.
The Better Thing 
I love how this describes how giving to others keeps us connected with Christ. Your comment about giving from what we have really resonates. We take our blessings in Christ for granted sometimes but to others we are offering something truly new and life-giving.
So true, thank you Alison.
