Mankind is so busy trying to justify themselves that they forget hear the plain teaching of God's Word regarding Righteousness (verse 3). Not of us striving to obtain it but of the substitution of Christ for us (verses 4-9). Paul the Apostle and the Old Testament Prophets all proclaimed the Gospel of Faith and its sound went unto all the world, and is available for all people but the issue is not availability but of the willingness to hear it (verses 16-21).
In this message we focus on the importance of being a people with open ears with open hearts willing and ready to hear what God says. In particular this needs to start with God's way of Salvation (Righteousness by Faith). We see in this chapter God is ready and willing to give the Gospel to all and will save whomever will hear it.
