This is an old Christian song. Today we are told it is irrelevant by some, that we do not need to prepare, clean house, stay awake or be ready. That is a lie.
 
How to have oil put in your lamp.
 
If you listen and do what the Holy spirit is telling you to do.
He will put oil in your lamp.
 
If you forgive others and apologize to others.
He will put oil in your lamp.
 
If you pay back the debts you owe, the ones you have been ignoring.
He will put oil in your lamp.
 
If you tithe to the church so the gospel can be spread to the unsaved.
He will put oil in your lamp.
 
If you pray for your enemies and the unsaved.
He will put oil in your lamp.
 
If you yield to Jesus and give him your habitual sin.
He will put oil in your lamp.
 
If you stop complaining and criticizing.
He will put oil in your lamp.
 
etc etc
 
Got oil?
