Grace...

"God's love was expensive. God's grace is free, but it's not cheap"*

Imagine someone knocking at your door... you answer it. "Hello. You've been given a free gift of a cruise ticket. I have plenty more where this came from, so if you tell other people about this, I can give one to them too. Would you like to accept this cruise ticket?"
"Of course", you say. What would you do with this opportunity now? Would you tell your friends about this cruise ticket offer? Or would you hoard it to yourself and not share the source of your gift? "Of course I would tell people," you say. "Why would I keep secret the source of an unlimited number of gifts?" It would be selfish, and mean to keep others from knowing that they could receive this same thing you had bestowed upon yourself. However, we do this every day. The gift is not a cruise ticket, but eternal life. We regularly keep secret our gift and its Source, and neglect to tell others about how they can receive the same thing. We hide our "ticket" in the closet, and live as if we care nothing for the One that gave it to us, showing no regard to His desires and plans for our lives.
We take Grace as something that is cheap and easy, something that we don't value, or care for. Dragging Grace through the mud, we say "If God forgives me, then I can keep doing this."
Or, just as bad, we ignore that God's grace entirely, saying "I have to make it on my own," "I'm not good enough to recieve God's grace", or "God doesn't care about me... I'm too bad."

No matter whether you trivialize God's Grace by pretending/insisting it doesn't extend to you, or by taking advantage of the fire-policy you percieve it to provide... you're still ignoring something. God's grace isn't something cheap and to be wasted... it's a precious gift from the Father of Lights, the God in Heaven who created all things, and after letting us choose our own path, watching us choose the sinful one, and seeing us in need of redemption, gave up his own son to die on the cross, that our debt might be paid, so that we can be restored to fellowship with Him.
