What is the Biblical Basis for God hard-determining human behaviour?

As an example of human behaviour: "and he ate" Genesis 3:6. ESV. A. Adam acted out of freewill. B. Adam's action was determined by God positively withholding from Adam the grace to obey Him and refrain from eating. God did this because He wanted to make the point that grace to obey would come through the 2nd Adam, and therefore God withheld it from the 1st Adam. 1st and 2nd Adam are mentioned in 1 Corinthians 15:45-47. >"And from his fullness we have all received, grace upon grace." John 1:16 ESV
