I know the OT says a person should not charge interest to God's people. Does this rule still apply to us today when lending money? What about if a affluent Christian purchases a rental home as an investment. What should he do if his tenant fails to pay rent? The Christian in this example would not be personally negatively impacted if he did not get the rent check for a given month (meaning his quality of life continues) but his overall return on that investment would of course be negatively impacted..
