'Service' in the Bible
Are not all the angels ministering spirits sent out [by God] to serve (accompany, protect) those who will inherit salvation? [Of course they are!]
They serve as a pattern and foreshadowing of [what has its true existence and reality in] the heavenly things (sanctuary). For when Moses was about to erect the tabernacle, he was warned by God, saying, “See that you make it all [exactly] according to the pattern which was shown to you on the mountain.”
Every priest stands [at his altar of service] ministering daily, offering the same sacrifices over and over, which are never able to strip away sins [that envelop and cover us];
Therefore, since we receive a kingdom which cannot be shaken, let us show gratitude, and offer to God pleasing service and acceptable worship with reverence and awe;
