Paul said in 2 Corinthians 8 that we are to excel in everything…in faith, in speech, in knowledge, in complete earnestness in our love for others---he said see that you excel in this grace of giving!
There is a measure of grace associated with the ability to assimilate this principle in your life. God gives us grace to give. We are to excel in it!
The question is how do we excel in this grace of giving?
You do it and you keep on doing it. The amazing thing about giving is that you don't have to believe in it for it to work. You sow, you reap. What you sow produces a harvest ALL the time.
Why not target some folks to "practice" giving on? As you step out with a generous spirit, you will find more and more grace to keep on being a giver. It's time to excel in the grace of giving!
