"And if Christ has not been raised, our preaching is useless and so is your faith."
-1 Corinthians 15:14

I would dare to venture that many, if not most, of us have yards and houses that need work on at least a weekend basis if not a daily basis. Assuming you are one of these people, like I am, allow me to submit an analogy.

Someone comes to your door, makes some observations about your yard/home and offers to pay for renovations. What is the catch? You just have to accept The Currency. For this situation, it is dollars. Let us say you accept. The great bonus is that the payment not only accounts for the lifetime treatment of the outside of your yard and house, but it also covers the inside of your home and all it's furnishings. The noticeable thing however is that your generous Provider went bankrupt supplying you that service; that gift. Hearing about this you wonder and fear - would He be able to come through on those promises? Fear not! A well established Bank supported Him and after a few days brought His business back.

If that Bank did not support Him and bring His business back after a few days, then all you and I would have is a well-intentioned Provider who went bankrupt in His devotion toward us. 

I hope you see that like the yard/house provider God provided payment for what was wrong with our "house" (life) - sin (rebellion). For our part, He simply asks we accept His Currency - His Blood and His Love. For His part, Father God (The Bank) gave His Son (The Payment/Provider) the authority/power to pick His life up again and He did. Thank God for the Bank that never runs out of The Currency - Love and His Blood.

Again - "...if Christ has not been raised, our preaching is useless and so is your faith." However, He is Risen....He is Risen Indeed!
