Scripture applies to all of us. It applies to the person who has never stepped foot in church as well as the person who was born in church. It applies to me and it applies to you. Although it may be difficult to swallow some of the teachings of Scripture, these teachings are still applicable to our lives. This includes this passage from Romans.
God did not only create Christians. He created those who have turned their backs on Him, as well. He loves them, and He loves us. He makes it rain on both the non-Christian and the Christian. As creatures of God, we have all sinned against God. We have gone our own way, and without our Creator, we have no purpose, no meaning, no hope. However, our Creator did give us purpose, meaning, and hope in the person of Jesus Christ.
When God sent Jesus to bear our punishment and rise from the dead, God formed the church and gave these followers of Jesus a purpose, namely to reach out to those still do not have any purpose, meaning or hope and telling them of God's love and His gift of eternal life available through Christ alone. In other words, God gave the church a purpose of finding the lost and bringing Jesus to them.
God also gave us meaning through Jesus Christ. Sin separated us from God and took away our purpose for living--to glorify God. It is impossible for an unholy people to perfectly glorify a holy God. We could praise Him and worship Him, but we could never truly glorify Him. However, when Jesus bore our sins, God reinstated our purpose. That is, through Jesus we can live holy lives, forgiven of our sins, glorifying God. We could not do this without Jesus.
Finally, God gave us hope through the person of Jesus. Jesus not only bore our sins, giving us purpose and meaning, but He also gave us hope of reconciliation with God. We can come to know God because of Jesus. No one else can do that. Christ will not force us to accept it. We must choose to accept it.
