Sometimes when driving on the expressway with my wife on board, I will change lanes without turning on my signal.  My wife will then point out my failure to do so.  Typically my reasoning for not signaling is there is no car around or behind me for 100 yards.  So although signaling a lane-shift, which is a warning to other motorists, is good to do,  it is not always  necessary. 

If your faith and trust in God is weak you might want a sign from Him for each time you are about to encounter a life-shift.  You know–a change that catches you off guard and brings about anxiety.  But the Lord realizes that if  He signals you everytime an event is about to occur, your faith will not be increased.  Hewbrews 11:6 reads, “But without faith it is impossible to please him: for he that comethto God must beliee that he is, and that he is a rewarder of them that diligently seek him.”  So if there is no sign, keep this in mind, He’ll show up on time.
