Numbers 3:38, The the outsider who comes near. This verse teaches the principle of the fear and reverence of YHVH when approaching his divine Presence. Other scriptures that teach our need to be careful when approaching him include Psalms 15:1–5; 24:3–5 and Ecclesiastes 5:1–2 (see also Gen 28:16–17; Exod 3:5; Lev 10:3; Josh 5:15; Ps 89:7; Heb 12:28–29).
As YHVH didn’t permit the Israelites to come near to him except through the intermediary of the Aaronic priests, similarly we can only come to our Father in heaven through the intermediary of Yeshua the Son of Elohim, and our Great High Priest (Heb 4:14), who is the spiritual door and way to the Father (John 14:6). Although, YHVH permits his set-apart ones (the saints) to come boldly before him through the agency of Yeshua’s high priesthood and his blood (Rev 5:6–8) to obtain mercy and grace in time of need (Heb 4:16), let’s not forget two things.
First, we come to YHVH Elohim in human weakness needing help and grace from him who is greater than us; therefore, we need to maintain a humble disposition.
Second, our Elohim is a consuming fire (Heb 12:29); therefore, we need to serve him with reverence and godly fear (Heb 12:28), since in his hands he holds the power of life and death (Matt 10:28). Fire is a biblical metaphor for judgment, and YHVH will judge all people including his own people (Heb 10:30–31) for all that they have done while in the flesh whether good or bad to determine levels of rewards and punishment (Matt 5:19; 16:27; 2 Cor 5:10; Rev 20:12; 22:12). In fact, Peter admonishes us to conduct our lives in the fear of Elohim and to be holy as he is holy who will judge each man according to his works (1 Pet 1:17).
