Describing the core message or summary of the Bible in a single article is hard, and inevitably leaves out a lot of important topics. But I’ll try. I’ll phrase six key themes of the Bible.
God is the Creator of the universe, of this earth and of our lives. Therefore, He deserves our worship (Revelation 4:11). If we want to know how we should live, we should ask our Creator.
2. The fall
Humanity turned away from God. Sin entered the world. This affects every single human being, and therefore we are guilty before God. We are separated from him, and we can’t live in his Kingdom as long as we are not reconciled to him.
3. God’s invitation and warning
Although humanity turned away from God, He sent his prophets to proclaim his will. These told the people to love God with all their hearts, and to love others as themselves (Deuteronomy 10:12, Leviticus 19:18). They called people to repent of their sins and to trust God (e.g. in Ezekiel 14:6). They warned the people that God’s judgment would come over those who kept rejecting him. But they also promised that God would send a Savior to reconcile humans with God. God showed his love for a world that rebelled against him (Romans 5:8).
4. God’s salvation through Jesus Christ
God sent his only Son, Jesus Christ, who was born of a virgin. Jesus taught people Who God is, and He showed his love and power. He died on the cross for the sins of all who believe in him, so that they could receive forgiveness of sins and eternal life (John 3:16).
5. The Holy Spirit
When Jesus returned to heaven, He sent the Holy Spirit. The Holy Spirit convinces people concerning their sins, so that they accept Jesus as their Savior (John 16:8-11). If people come to faith, the Holy Spirit comes in their lives and leads them in God’s truth (John 16:13). He forms believers from all over the world into the one Church, the body of Christ.
6. God promises a new earth
Jesus will return. This will be on “the last day” (John 6:40). All humans will then be raised from death, and Jesus will judge them. The unbelievers will be lost forever. But whoever believes in Jesus, will live forever in God’s Kingdom, on the new earth where there will be no more death, illness or tears (Daniel 12:2, Revelation 21:4).
