"looking back"

Lk 9, 61f.: "And another also said, Lord, I will follow thee; but let me first go bid them farewell, which are at home at my house. And Jesus said unto him, No man, having put his hand to the plough, and looking back, is fit for the kingdom of God."

When we think to look back, what's the problem?

Just like ploughing, following Yeshua needs full focus on the kingdom of G-d and on what is ahead. Saying Good-by to those that stay behind at home in this case is not a step in following Yeshua, but is opposed to it.

Lot's wife looked back and became a pillar of salt. She disregarded the warning of the angels, not to look back.

Was the Israelites' looking back to Egypt the cause of their murmurings?

Does this kind of fatefull looking back contain an element of regret of the choosen way paired with a lack of faith and vision?

If G-d calls, one shouldn't look back. Answering to G-d's call is never a wrong decision! He knows very well from where and to where He is calling us.
