The stone used as a pillow now becomes a memorial to his meeting with God in that remote place. Jacob says, I will never forget this day, and the pillar is set up as a sort of altar.
Every believer looks back at the time of his conversion, whether he knows the precise day or not, as the greatest day of his life. It is a day which he will remember for all eternity, as the day when God washed away all his sins and gave him the gift of eternal life. Then he understood for the first time what Christ accomplished on the cross. Then he had his guilt taken away, and rejoiced at the certainty of an inheritance which is kept secure for him in heaven. It may have taken place in an obscure place which is special to no one else, but it is special to us because God dealt with us personally there. It is not superstition to do so. It is simply a recognition of the fact that God is the God who intervenes in the lives of His people. We love his interventions because they are so personal, and we are nor lost to him in some great crowd.
I remember two or three years ago a man came into the vestry to see me after service. He was English but he was pastoring in America and he'd brought his son with him who was I think 19, and he had brought him because he wanted him to see the place where the Lord spoke to his father. And the son seemed to me to be very moved. That is a good thing. You can retrace your steps and rededicate yourself where God very first spoke to you. That is what was behind Jacob's pillar.
