The writer of the song, Steve Croft, and I made a parallel between this Hebrew law and the Christian life. We have been bought with Jesus' blood, so our salvation is NOT free. We have an obligation to follow our Lord's commands. That is how we show our love to God, just as the slave wanted to stay with his master out of love for him. We should live our entire life for the glory of God. Although our commitment to Him does not involve a literal ear piercing to show our devotion, it involves a deliberate decision to follow him.
If anyone is interested in a copy of my message, I will be happy to email you a copy.
