This is from my study bible by Max Lucado:

"What is the grace of God? The Grace of God

says you serve God because you're saved,

not in order to be saved. You love people

because you're save, and not in orde to be saved. You're

not trying to keep a legalistic system, you're responding

to a system of love and peace.

What is Grace? It's someone gives out of the

goodness of his heart , not out of the perfection of ours.

The story of grace is the good that says when

we come, he gives. That's what grace is.

Grace is a pleasent  surprise. Grace is a kind gesture. Grace

is something you did not expect. It is something you

certainly could never earn. But grace is something you'd never turn down.

You know what happens when someone sees the grace

of God? when someone really tastes the forgiving and

liberating grace of God? Someone who tastes God's grace

is the hardest worker, the most morally pure individual,

and the person most willing to forgive.

Always remember that Jesus says, 'My grace is deeper

then your sins.' "  ~ Max Lucado
