service though hidden.
In the gospels, Jesus often grew angry at those who worshipped God for the praise of others. He taught that if we fasted, we should not put on sackcloth, and ashes, but rather, wash ourselves, and carry on business as usual. In the epistles, this concept is broadened to include all types of works. Whenever we do something, we should not seek praise for it. We should be anonymous. We should be hidden.
This goes against everything the world teaches. The world wants to express it's gratitude for the things you do. you make a donation to a charity, they want to place your name in the paper. you help an old lady across the street, it's a human interest story on the 6oclock news. The world wants to recognize you, place praise on you, and in general, worship you for your good works.
It's so sad that so many Christians fall for it. Never realizing, that by doing so, they've already received their reward for that. They recieved it in the praise of the world, rather than the praise of Christ. As a Christian we should ensure that we are always in a state of humble service, never broadcasting what we've done. Rather when you do a good work, hide it under a basket. Again, this flies in face of worldy wisdom.
Let your good works, be hidden, and your bad works come to light. For you will receive praise from Christ for the hidden good works, and He will help you overcome, deal with, and move on from, your bad works that you bring to Him.
