A 21 year old young man gave a call as he was under depression and was suicidal. This is how the quick conversation went:

 I have done lot of wrong things in my teen years and because of that I am under heavy guilt and I am not at peace. 

Do you want to know how I dealt with the guilt of the past?

Yes Sir

Suppose you have taken a huge loan from your friend which you are unable to pay and it has become and heavy burden and your friend says I cancel your loan. You got it for free but who Paid the cost?

My friend. 

So would you agree that the one who forgives pays the cost?

Yes 

So when God forgives who pays the cost?

God.

Did God pay the cost for the forgiveness of our sins?

I don’t know

It is Jesus who paid the cost for the forgiveness of our sins on the cross so that we can be free from the burden of guilt and sin.
