1 Peter 4:10  As each one has received a special gift, employ it in serving one another as good stewards of the manifold grace of God.

You do special things for others and question why they don't return the same to you. Have you ever had that thought? It can be painful to not receive the same kind of blessing you bestowed on others. When you are empty handed, you question why they haven't returned the favor. 

Today's scripture helps answer your question. God provides each person talents and He oftentimes ques us to perform those acts of kindness. Not everyone has the same gift to give back your specific blessing. Let's face it, not everyone has a heart like yours. 

Luke 14:14 and you will be blessed, since they do not have the means to repay you; for you will be repaid at the resurrection of the righteous."

Your acts of kindness represent your heart. Thankfully, God created each person with a different heart. You might not receive back the goodness you've given, but God sees your generosity and will reward you one day in Heaven. Keep on giving without an expectation to receive. Keep adding to your Heavenly rewards.
