Scrimping on the Lord

When you've counted all things as loss on account of Christ, that would be the most reasonable service.  But when you tried to count everything that you've given or exerted for the Lord's sake, it wouldn't be meaningful anymore.  The Lord has given Himself, even His own life for us, it was not for His own sake, but for us.  Who are we?  The things that we've given, the time that we've spent, the life that we've offered to the Lord, all should be given freely.  The Lord deserves our best love!  But oftentimes we would scrimp when it comes to offering ourselves, our time, or our riches to the Lord.  It seems that the Lord doesn't deserve the best.  It seems that we are the master and the Lord is our slave and fits only the droppings from our table.  What is all these in exchange of what He'd given us?
