(Exo 19:1-25) Mosaic law came 430 years after the Abraham covenant; the covenant doesn't abrogate God's promises to Abraham (Gal 3:13-15). Abraham marks to start of the Age of Israel which extends to the time of Christ. The church has not replaced Israel. Abrahamic covenant showed the way of faith (Rom 4:1-3, Gal 3:6) through the writing of scripture. The law shows us our sinfulness (Rom 5:20). Preparation for receiving the law (Exo 19:1-2); Moses is the mediator a picture of Christ (Deu 18:15). Angels were also mediators (Gal 3:19; Act 7:53, Heb 2:2). Men need a mediator (Job 9:32). Job knew the mediator was coming (Job 19:25-26). Christ is the ultimate mediator (1Ti 2:1-7). A mediator is equal to both parties. Christ knows us best, understands everything, and still loves us. He has given us one law -- the law of faith (Jam 4:11). God initiated redemption and reminds Israel of His protection -- "wings" represents God's care and deliverance (Exo 19:4, Psa 17:8, Psa 91:1). God is pictured as the father eagle (Deu 32:10-12). God's objective is to produce a unique people (Exo 19:5-9). Jesus warned that Israel failed the conditional Mosaic covenant (Mat 21:42-44). Peter explains that Divine purpose carried foward to the new covenant -- producing a unique people -- the purpose passed on by Grace through faith (1Pe 2:2-10). The flaw in the law (Rom 8:3) was the flesh -- it could not impart power to keep it. The law can command but cannot enable, save, justify, nor make righteousness; it only shows the barrier (Exo 19:10-25). Moses was unique as prophet (Deu 34:10); only One would surpass (Joh 1:14). The merits of Christ are the basis for the new covenant.
