23 Nov 2 Corinthians 8:7

7 But just as you abound in everything, in faith and utterance and knowledge and in all earnestness and in the love we inspired in you, see that you abound in this gracious work also.

It is important for Christians to continue to grow in their spiritual lives. If we are in the same place as we started when we surrendered our lives to Him, then we need to take a look in the mirror. As we grow, we grow in our giving and the understanding of generosity. We should not only be growing in the grace of generosity but sharing it with people. In this particular context the Corinthians were more affluent than the Macedonians. Therefore, they could give more generously, and this is what Paul expected to happen.
