From Romans 1:18 to 3:20 Paul gives the bad news: humanity is not righteous in God's eyes and left to ourselves we will be condemned on the day of judgement. But from 3:21 Paul gives the good news of the gospel: now a righteousness from God is available to all those who trust in what Jesus did on the cross. This passage is full of Christian jargon words like "righteousness", "faith", "grace" and "redemption", and so during the sermon these words are carefully defined to make things clearer.
