We are bound by the limits of our fallen nature, which makes us spiritually “dead in our trespasses and sin”.
We are not spiritually sick, but dead.
Free will, therefore, is a myth apart from God’s grace giving us the option to choose Him …
Because a dead man has no choice in and of himself.
Fundamentally, we have no human autonomy or ability to choose anything apart from what God has chosen to delegate and enable.
According to His sovereign will, however, He didn’t want puppets on a string …
So He gave Adam the option to choose sin and death – as He knew he would – by rejecting His rule.
Adam chose foolishly.
Christ, according to His eternal plan …
Then defeated sin and death through the Cross to give us the option to choose righteousness and life – as He wills – by submitting to His rule.
This is what makes God’s grace so amazing.
