Some quotes from the book "Grace" by Max Lucado.
"To accept grace is to accept the vow to give it."
"Grace is not blind. It sees the hurt full well. But grace chooses to see God's forgiveness even more. It refuses to let hurts poison the heart. Where grace is lacking, bitterness abounds. Where grace abounds, forgiveness grows." (check out Hebrews 12:15)
"As long as the cross is God's gift to the world, it will touch you but not change you. Precious as it is to proclaim, 'Christ died for the world,' even sweeter it is to whisper, 'Christ died for me.'"
"Grace is God walking into your world with a sparkle in His eye and an offer that's hard to resist. 'Sit still for a bit. I can do wonders with this mess of yours.'"
