God Justifies the Ungodly

Romans 4:5-8 "Now to the one who works, wages are not credited as a gift but as an obligation. However, to the one who does not work but trusts God who justifies the ungodly, their faith is credited as righteousness. David says the same thing when he speaks of the blessedness of the one to whom God credits righteousness apart from works: 'Blessed are those whose transgressions are forgiven, whose sins are covered. Blessed is the one whose sin the Lord will never count against them.'" * Is the man of lawlessness Satan or a person? * Is God's love different for believers and unbelievers? * Aliya calls about her school tests, but she's feeling overwhelmed. * If we are no longer considered sinners after we accept Christ, why do we still continue to sin?
