1 Timothy 5:24-25(NIV)
24 The sins of some are obvious, reaching the place of judgment ahead of them; the sins of others trail behind them. 25 In the same way, good deeds are obvious, and even those that are not obvious cannot remain hidden forever.
One of the hotel booking companies has a marketing campaign in which they have somebody who always states the obvious. In this world, there will always be some form of deception or a situation where we are naive and the obvious is not very obvious to us at all. In this world, some of what would be considered sinful has now been accepted and is now considered normal.
The Bible says that the sins of some are obvious. There are those that are trying to hide sin and think that it can remain hidden. To the world, it can be hidden, but God sees it all. To Him, everything is obvious and nothing can be hidden from His sight. The good deeds that we can do are also obvious. The point is that we don’t need to try to be noticed for doing something good just as Jesus did not desire attention for helping others.
