According to the late Ray Dillard, professor of Old Testament at Westminster Seminary in Philadelphia, one of the great themes of the Bible is the question of whether the covenant with God is conditional or unconditional.
It is this question and this tension which drives the Old Testament.
There are places where it seems that God says to his people: “It’s conditional. You have to obey me. I’m a holy God. I can have nothing to do with sin. If you want to be accepted by me, or have a relationship with me, then you have to obey me.”
There are other places where it seems that God is saying: “No matter what you do, I am going to be faithful to you. I will be there, I won’t give up on you, I will save you.”
So which is it?
In a way, you could say that the entire Old Testament is one big plot thickening, in which the big question is: Can we have a relationship with God? And if so: is our relationship with him conditional or unconditional? Is it that we have to fulfill something, or is it that he loves us no matter what?
So what’s the answer?
The answer is actually not found in the Old Testament. It it when we get to the cross of Calvary that the answer is revealed.
The answer is… YES.
It’s not one or the other, it’s both.
The covenant with God is BOTH conditional and unconditional.
In the death of Jesus on the cross you find that you have to take both the conditions of the covenant and the unconditional nature of God’s love seriously at the same time.
Jesus satisfied the conditions of the covenant on our behalf so that God could accept us and love us unconditionally.
