That's not atonement. That's restitution. There is a difference.
Ultimately all sin is sin against God and His holy standard. How do you atone for sin against almighty God?
Atonement as per the OED 1933-1955:
1/ The condition of being at-one with others; concord, agreement. 1623
2/ The action of setting at one, or being at one, after discord; reconciliation. 1685
3/ (specifically in theology) Reconciliation or restoration of friendly relations between God and sinners. 1526
4/Propitiation by reparation of wrong or injury; amends, expiation. 1611
My point here is that it is all too easy for Christians to take the lazy way out. Do you think thats what God wants - talk instead of action? I dont think so.
