The idea of middle knowledge is a construct of philosophical speculation, and includes all of the possible choices of all autonomous creatures. For example, if Van was given the choice of suffering torment for his many sins, or trusting that Christ would deliver him from his deserved punishment, Van will choose to trust in Christ. Therefore if God actualizes that world of possibilities circumstance, then God knows beforehand that Van will choose to trust in Christ.
What neo-Molinism does is to claim middle knowledge also includes "might counterfactuals." For example, if Van was given the choice of suffering torment for his sins, or trusting that Christ would deliver him from his deserved punishment, Van might choose to trust in Christ.
This moves the actual choice from the meta-physical to the actual reality we experience, but removes the fixed and foreknown aspect of the future. However, this removal then inserts the decision agent's responsibility for his or her sinful decisions and their consequences.
