Wikipedia says “Burn the ships”  means the ‘point of no return (PNR or PONR) is the point beyond which one must continue on one’s current course of action because turning back is dangerous, physically impossible or difficult.’  October of 2018 For King and Country released a song called Burn the Ships. You can listen to it here:

Jesus spoke about leaving things behind, forsaking people and things in Luke 14:25-27.

Many people were traveling with Jesus. He said to them, “If you come to me but will not leave your family, you cannot be my follower. You must love me more than your father, mother, wife, children, brothers, and sisters—even more than your own life! Whoever will not carry the cross that is given to them when they follow me cannot be my follower.”

We must love Him MORE THAN anything and anyone else we know and love. In 1982 I wrote We Must Go On © Molly Lin Dutina 3-15-82

It doesn't matter.
We must go on.
If they won't come with us,
we must go on.
Pressing together
into the Kingdom.
We must go on.
Our Master Calls.

We can try to tell them,
but we must go on.
Can't let earth hold us back
we must go on.
The Father soon will speak,
Jesus will come.
It doesn't matter
we must go on.

If we feel hurt and loss
we must remember:
the Father works 
for their salvation
every hour of every day.
We must obey - we must go on.

Burn the ships, forsaking all others, follow Christ. It still applies today!
