2Co. 9:8 And God is able to make all grace abound to you, so that in all things at all times, having all that you need, you will abound in every good work.
The grace of God is supposed to make a Christian to abound in every good work, in all things and at all times. Grace is God extending His finger or Spirit to us, so that through the power of the Spirit we become able to do things that a human being couldn't normally do. The number one thing we should use the grace of God to do is to become perfect in character. Of course, the grace of God also makes it possible for us to do all manners of miracles.
Lk. 19:13 So he called ten of his servants and gave them ten minas. [A mina was about three months’ wages.] `Put this money to work,’ he said, `until I come back.’
The Parable of the Mina is about how we put the grace of God to use.
