God can intervene in human affairs to bless people who follow His law. He did this with Israel every day for 40 years in the wilderness. In that example, He made sure that when Israel gathered manna each day, that a person who gathered a lot had plenty but those who gathered a little also had plenty. This is compared to the summary of communism, "From each according to his ability and to each according to his need.", enforce by government coercion and violence.
