I've always associated lighthouses with the Lord. He is a strong tower that we can run to. And His light always points the way to safety. He is a beacon that shines His bright light into the darkness.
Today, I came across this old hymn, "Jesus is the Lighthouse". Here is the chorus:
Oh, I thank God for the lighthouse
I owe my life to Him
King Jesus is the lighthouse
Upon the rocks of sin
He has shone a light around me
That I could clearly see
If it wasn't for the lighthouse
Then where would this ship be.
