WALT KAM ~~ when the title "LORD" is all capitalized it refers to Jehovah. See the Foreward or Preface of Bibles. "Lord" refers to Jesus. The name Jehovah was removed over times by superstitious translators, for fear of defiling the name of God.
Serving The Lord is different to serving others. When we serve others with no thought for doing the Lord's Will, we may finish up in servitude to others' selfish demands. Answers to prayer come often while serving The Lord in His Way.
