When reading the Bible, there is certainly one thing that will come across quite obviously.
It is certainly not a book that has only profound teachings and wise practices.
Rather it is a book that also has accounts of human faults and failings.
There are accounts of human sinfulness, even grave human sinfulness.
In the 1st reading is the account of the first murder and killing.
It was a crime that is committed by one brother on his only other brother.
What is even more puzzling is that God had warned Cain, when God said to Cain: But if you are ill disposed, is not sin at the door like a crouching beast hungering for you, which you must master?
But Cain did not heed the signs that God gave him, and went on to commit that grave crime.
In the gospel, when the Pharisees demanded from Jesus a sign from heaven to prove His identity.
But Jesus did not give them the sign, because enough signs have been given.
As for us, we will know the signs when we get a hold of our conscience.
Let us not end up sighing in regret for not heeding the warning signs that God is giving us.
