MATTHEW 6:1-4
The motive behind our gift is more important than the gift itself. Paul said if he gave all of his goods to feed the poor, or if he made the ultimate sacrifice of giving his own life for someone else, and wasn't motivated by love, his gift would profit him nothing (1 Corinthians 13:3).
Many Christians give faithfully but never see the hundredfold return that the Lord promised because of wrong motives (Mark 10:29-30). Paul said God loves a cheerful giver - not one who gives grudgingly or out of debt (2 Corinthians 9:7).
Jesus gave us the key to purifying our motives in this same teaching. He said, "But when thou doest alms, let not thy left hand know what thy right hand doeth" (Matthew 6:3).
Giving in a way which we will not receive recognition for our gifts will guarantee that our motives are right and grant us the true joy that comes through selfless giving (Acts 20:24).
Ask the Lord for an opportunity to give a kind word or a helping hand to someone who will not be able to repay and others will never know about it. This could be some driver in a traffic jam, a co-worker, a spouse, a child who won't even notice a kind deed, or any number of other people. Opportunities are all around us.
