"Let" means permit God to do what He wants in us (Col 3:15-16). Aspects important when when we look at scripture: (a) we need honesty (humility) - He's the only One who can impact our lives; (b) accuracy - rightly dividing the Word; (c) assume relevance - what we read applies to us now; (d) what we read is practical - we need to obey the spirit behind the letter. The greatest promise in scripture: "You will see me: because I live, you will also"... "and he that loves me shall be loved by my Father, and I will love him and will manifest myself to him" (Joh 14:19-21). The Word of Life is that which was manifested to John but can be to us (1Jo 1:1-4). Similarly, the Lord manifest Himself to Moses (Exo 33:12-23).
