The plan A from the Old Testament was God paying your debt with his greatest love -His son.
"10 Yet it was the Lord’s will to crush him and cause him to suffer, and though the Lord makes[a] his life an offering for sin, he will see his offspring and prolong his days,
and the will of the Lord will prosper in his hand."
"21 God made him who had no sin to be sin for us, so that in him we might become the righteousness of God."
when told from Mark 1:14-15
"Repent and believe the good news!”
