After the fire there was a tiny whispering sound.
When he heard this,
Elijah hid his face in his cloak
and went and stood at the entrance of the cave.
A voice said to him, "Elijah, why are you here?"
He replied, "I have been most zealous for the LORD,
the God of hosts.
But the children of Israel have forsaken your covenant,
torn down your altars. 1Kings 19:12-14
Elijah found out that seeking God in the elements was not to be found, but in a tiny whispering sound. He hid his face. Elijah already has a deep relationship with the Lord, but he's asked why he was there. And Elijah tells him he wants more, because of what he witnesses from those who forsake the Lord.
When we have a deep and abiding love for God, we are like Elijah, seeking God in all things. But it is in the tiniest whisper where we will hear him. It is in our zeal that we seek to bring the lost children back to the Lord. It's true, when we love deeply we want to give more of ourselves. Men and women who fall in love know this, they give of themselves for the one they love. When that love is not there we end up seeking from someone else. That's why Jesus used adultery as an example in the Gospel today. If we are fickle with those we love in our relationships, how about those who stray from God, to love and worship another entity. Are they not committing adultery too. After all they are worshiping something that is not of God.
We have been created to be one as man and women are one joined by the grace of God. Just as we are joined to God within our souls. Committing adultery is an act against those we love and against God whose love is everlasting. We destroy our own souls when we go against God.
