To benefit from God's promises, though, we must understand the role Jesus Christ plays in our salvation and exercise faith in him. Jesus himself said: "God loved the world so much that he gave his only-begotten Son, in order that everyone exercising faith in him might not be destroyed but have everlasting life." (John 3:16) Pointing to the central role of Jesus Christ in this matter, the apostle Peter said: "There is no salvation in anyone else, for there is not another name under heaven that has been given among men by which we must get saved." (Acts 4:12) The apostle Paul and his associate Silas urged a sincere inquirer: "Believe on the Lord Jesus and you will get saved, you and your household."—Acts 16:30, 31.

Jesus saves because he died for us. And what a valuable provision his death is! When we see it as a part of God's solution to the complex problem of Adam's sin, our faith in Jehovah and his way of doing things is strengthened. Yes, Jesus' death is a means of rescuing "everyone exercising faith" in him from sin, disease, old age, and death itself. (John 3:16)

So, what does "accepting" Jesus really mean? Is it a one-time act of faith, or is it a continuing way of life? Must our belief be strong enough to motivate us to action? Can we really accept the benefits of Jesus' sacrifice without the responsibility of following him?

We must hold firmly to our Christian faith because, unlike what you may hear in some churches or on religious television programs, the Bible says we can fall away. It tells of Christians who abandoned "the straight path." (
2 Peter 2:1 , 15 ) We thus need to 'keep working out our own salvation with fear and trembling.'— Philippians 2:12 ; 2 Peter 2:20 .
Is this how first-century Christians, the people who actually heard Jesus and his apostles teach, understood the matter? Yes. They knew that they had to do something. Jesus said: "Go therefore and make disciples of people of all the nations, . . . teaching them to observe all the things I have commanded you."—
Matthew 28:19, 20 .
We do not earn salvation by doing these things, for no human could ever do enough to merit such an astounding blessing. We are not worthy of this magnificent gift, though, if we fail to demonstrate our love and obedience by doing the things that the Bible says God and Christ want us to do. Without works to demonstrate our faith, our claim to follow Jesus would fall far short, for the Bible clearly states: "Faith, if it does not have works, is dead in itself."—
James 2:17 .
