[Ali Imran]

Ali, given that you're theologically astute, you knew full well that I used 'ransom' as a metaphor for the blood of Jesus Christ that provides the payment for our sin debt and not using it in monetary terms. His blood is the only 'spiritual detergent' that can remove the stain of sin.

The cross of Jesus Christ represents the intersection of God's love and God's righteousness. The willingness of God to sacrifice in order to reconcile us to Himself is a demonstration of His love and spiritual amnesty for us. But the cross also represents God's righteousness, which demands a payment for our sins. Someone has to pay for our sin, and the cross is the place where Someone did.

As Paul wrote, 'Much more then, having now been justified by His blood, we shall be saved from the wrath of God through Him' (Rom 5:9) The unbeliever who has rejected or simply neglected God's offer of salvation through Christ first of all callously dismissed God's desire for a relationship. He's also 'trampled underfoot the Son of God.' (the phrase means to treat as worthless) 'Not believing the right things about Jesus' isn't some minor offence but is tantamount to rejecting and declaring Christ's death to be worthless.

Yes, of course it's not money but payment nonetheless. God demands payment and God pays for it. That is exactly like how I described it earlier. 

And another thing. What you are describing there shows that there is no forgiveness in Christian theology. God cannot just forgive us when we do wrong. As you've said, our sins must be paid, and God paid for them himself, which is illogical when we are talking about God who owns everything in the universe. He cannot just forgive. Sin must be paid with blood.
