From today's devotional
The Corinthian believers excelled in everything they had-faith, good preaching (speech), much knowledge, much earnestness, much love. Paul wanted them to also be leaders in giving.
Giving is a natural response of love. Paul did not order the Corinthians to give, but he encouraged them to prove that their love was sincere.
When you love someone, you want to give him or her your time and attention and to provide for his or her needs. If you refuse to help, your love is not as genuine as you say.
