God freely wants to extend forgiveness and mercy
if the greatest commandment is to love God supremely with our whole being, then the greatest sin is to not do so.
These statements are mutually exclusive.
Faith is a condition of salvation
And this cuts to the heart of the matter. The ultimate requirement is faith, worship of Him. Moral choices, good works, well-treatment of the world and your fellow-man - none are adequate to gain salvation unless you add faith and worship and love of God.
The freedom and will to have great good and love implies the equal necessity to be able to misuse this gift of will for great evil or selfishness. The alternative is robotics who cannot love, relate, be responsible, etc.
But by the argument you've laid out, with love of God being a condition of salvation, then God does not appreciate free will when it is used to make the choice, not to commit any morally objectional behavior or break any other tennent of His law, but simply not to worship or love Him. By doing so, the Ransom is not an free act of generosity and loving kindness. That sacrifice and offer of redemtion does come with a price, but the cost is to us, not to Him.
We are not condemned because Adam sinned, but because we personally sin (Rom. 1-3).
I return to my argument that inherited sin is an unjustified punishment of mankind and the ransom sacrifice of Christ Jesus is God offering a conditional pardon, calling it magnanimous and expecting praise for the entire business. By creating that requirement that Redemption is unavailable not for a sinful act but for the lack of worship, the act of worship becomes not an selfless act of of a loving creation for our loving Creator but the coin with which we buy Redemption, else we face the eternal death that comes with the lack of it. We are condemned, not because we sin, but because we do not bend our knee to Him.
