God's Special Possession

We're going to look at a controversial topic today called predestination. We read in 1 Peter 2:9, 10 "But you are a chosen people, a royal priesthood, a holy nation, God's special possession, that you may declare the praises of him who called you out of darkness into his wonderful light. Once you were not a people, but now you are the people of God; once you had not received mercy, but now you have received mercy." As the bride of Christ we've been set apart -- we are a chosen nation -- to express Christ on this planet. Peter sits it atop the mercy of God. * So many teach that you can walk away from Jesus - lose your salvation. What is the biblical truth? * I heard Rhonda Rousey speak about wanting to commit suicide after losing her fight. I thought that it was sad her identity was being a fighter. Please explain identity in Christ. * There's so much garbage on social media. How do I respond to those posts and share Christ?
