Kingdom of heaven is like the ten virgins who took their lamps and went our to meet the bridegroom
Foolish ones did not bring extra oil
Wise ones took extra oil in their vessels
They all slept while they waited
At midnight they heard a cry: "the bridegroom is coming! Go out to meet Him!"
The foolish virgins did not have enough oil. They asked for some of the wise virgins oil.
The wise virgins would not share because they did not have enough for both of them.
So the foolish ones went to buy more oil, and while they were gone the bridegroom came and those who were ready went into the wedding and the door was shut.
They came to Him crying and He told them He did not know them.
Watch because you do not know the day or the hour He is coming.
Jesus is telling His disciples these things. Men who are learning from and following Him.
We don't know the details - all this is a part of trusting our lives to Him.
Our job is to be ready. Oil represents the Holy Spirit in the bible. That is Who Jesus sends to His followers to be with us when He goes back up to heaven. The Holy Spirit is Jesus gift to us.
We don't want to be in the middle of doing out own things and not being ready when He returns. Following Jesus is a life long walk. Faithfulness and being prepared are key to living life with Him.
