When a bottle of liquid has a skull and crossbones on it, one should be smart enough not to drink it. If one notices the sign "slippery when wet," one should be smart enough not to speed that way. If the shark tank has "no hands allowed," one should be smart enough not to put a hand in there.
The point of all this is that we wish people would learn without having to suffer the consequences of being hard headed. A man may know the risk of picking up hookers but not learn his lesson until he is arrested or is a victim of a transmitted sexual disease (Proverbs 5:11-13). If the word is out, "Don't send text messages while driving," man should learn from those words and not from having an accident.
In Luke 15:11-32, we read of a young man who demanded his inheritance and wasted it after moving far away. This young guy didn't listen to anything until he was broke, alone, and sitting among the pigs, desiring the slop they ate. Likewise, the word of the Lord warns men, but are we listening? (Prov. 1:20-33; Prov. 22:3).
Hope to hear from you or see you at the services.
