“For I delivered to you as of first importance what I also received: that Christ died for our sins in accordance with the Scriptures, that he was buried, that he was raised on the third day in accordance with the Scriptures…” (1 Cor 15:3-4)
The Bible says that everyone on this planet is a sinner (Rom. 3:23). That means that everyone, even you and even me, has done and thought things that are abhorent to God. It also means that we have not done and not thought things that are pleasing to God. This means that the reality of our situation before God is that we are dead in our sins (Eph. 2:1), unable to please God and even at war against Him (Col. 1:21), and headed for the punishment due those who war against God (Matt. 10:28).
God’s Response to Our Need
Out of his great love for the world and the people that he created (Jn 3:16), God the Father sent his son, Jesus Christ, to live with us as fully man and fully God. Jesus lived the perfect life (Heb 4:15), was crucified and died and was buried, and three days later rose from the dead (Matt 28:6; Mk 16:6; Lk 24:6). Having lived the perfect life and still died a sinner’s death, Jesus is able to cover the sins of others with his blood (Rom 5:9; Rev 1:5) and give them his righteousness (Rom 4:5).
Our Response to God’s Gift
The proper response to what God has done for sinners through the life and death of Jesus Christ is faith. We are to believe what Jesus said and did. Anyone who believes in Jesus is a child of God and will someday go to be with him in heaven (Rom 10:9). If you believe, you have been adopted into his family (Eph 1:5) and are a new creation, cleansed from your sins (1 Cor 6:11; 2 Cor 5:17).
