Job 35:6 If you sin, what do you accomplish against Him? Or, if your transgressions are multiplied, what do you do to Him? 7 If you are righteous, what do you give Him? Or what does He receive from your hand? 8 Your wickedness affects a man such as you, And your righteousness a son of man.
A lot of people think that we scratch God's back if we do good and righteous things; that we are doing Him a favor. Now, He owes us and must repay us with salvation.
Nope. God is not injured or lessened by man's sins. Nor does He profit or become greater by our righteousness. These only affect our fellowman. Salvation is not a divine payment issued to us for doing God a favor. Salvation is by grace (Eph 2:8, Romans 6:23). Grace means favor granted to those who deserve the opposite.
In salvation, it is God who scratches our back even though we deserve to be pushed and kicked around with divine judgment.
