We should be in awe before God, who will punish us if we reject him.

Hebrews 12:25-29

25 Beware that you do not refuse to listen to God who is speaking to you. The Israeli people did not escape God punishing them when Moses (OR, God) warned them here on earth. So we shall surely not escape God punishing us if we reject him when he warns us from heaven! [RHQ] 26 The earth shook [PRS] then when he spoke [MTY] at Sinai Mountain. But now he has promised, “I will shake the earth again, one more time, but I will shake heaven too.” 27 The words “again, one more time” indicate that things on earth will be shaken {that he will shake things on earth}, meaning that he will set aside all that he has created, in order that the things in heaven that cannot be shaken {that nothing can shake} may remain forever. 28 So, let us thank God that we are becoming members of a kingdom that nothing can shake. Let us worship/serve God in a way that pleases him by being greatly in awe [DOU] before him. 29 Remember that the God we worship/serve is like a fire that burns up everything that is impure [MET]!
