Jesus is our mediator to God because He is God. Heck, I can't even get in to see some lowly local county official without special reason, coordination and scheduling – yet, I have 24/7 access to the King of Kings! Are you blown away by that yet? What a God we serve. God is powerful – yes; all-knowing and all present – yes; but also merciful and compassionate.
Don't be afraid to come into His presence. Don't think you have to wait until you are clean and perfected to meet with Him... He takes you as you are. He does the cleaning, He does the perfecting. Just go to Him. No one can make you love Him, and sitting in church as a dutiful response to some church law doesn't cut it either. Give your inner being over to Him and He'll take it from there. Wow – you get a seat right in front of the King. Doesn't get any better than that! Endure the fire...it's producing pure gold!
