Romans 8:38-39 tells us that nothing can separate from the love of God in Christ. Yet sometimes we feel that our sin does. I am not talking about the sins you have committed before you became a Christian. I am talking about the sin you commit as a Christian even the ones you struggle with. Like it or not, every Christian struggles with sin. No one is exempt. Even the Apostle Paul wrote about his struggle in Romans 7. If you think your sin will somehow separate you from the love and acceptance God has for you, please read these words from J.D. Greear from his book, Gospel:
Our sin and our failures have not, and can never again, separate us from Him. He has put them away forever, as far as the east is from the west (Ps. 103:12). We have been credited, once and for all, the righteousness of Jesus Christ. He has said to us in Christ, "You are My beloved child. In you I am well pleased...I will never leave you or forsake you," and "surely goodness and mercy will follow me all the days of your life. You will dwell in My house forever" (Matt. 17:5; Heb. 13:5; Ps. 23:6, author paraphrase)
The Gospel is good news for all Christians because God has dealt with all our sin, past, present, and future, and no matter how many good days and bad days we have, we are never separated from the love of God in Christ.
