"but God shows his love for us in that while we were still sinners, Christ died for us."
This is God's love: The Son of God died on a tree in place of me (1 John 4:9-10). The Son of God gave his life in exchange for mine. The Son of God experienced His Father's judgment and wrath instead of me. Love... Love that is out of this world. Love from God while I was still a sinner (ungodly, under God's wrath, an enemy of God - Romans 5:6,8,9,10), Christ died for me. That is love, and that is the good news.
It had nothing to do with my decision either, because God decided to love me in this way without consulting me. If the LORD had said to me, "What do you think if I send my Son, and have Him die instead of you?" I probably would have said, "No! I'll pay for my own sin. Thank you." But God didn't ask me, instead, He sent Christ into the world as a baby, and the Lord Jesus arrested my heart with His love (Galatians 2:20; Revelation 1:5-6).
"For if while we were enemies we were reconciled to God by the death of his Son, much more, now that we are reconciled, shall we be saved by his life." (Romans 5:10 ESV).
This is good news of great joy (Luke 2:10) and it is worth preaching (proclaiming) to the world!
Grace, peace and love to all who treasure Jesus with lasting joy.
