“Believe on the Lord Jesus”

Those Christian missionaries opened the jailer’s mind to a fundamental truth about salvation. It was the same truth that the apostle Peter explained when the Christian congregation was first established. Peter pointed to the central role of Jesus Christ in the matter of salvation, calling him “the Chief Agent of life.” That apostle also 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 3:15; 4:12) Paul and Silas directed the Philippian jailer to this same Agent for salvation when they said: “Believe on the Lord Jesus and you will get saved.”​—Acts 16:31.

So, then, what is required for salvation? The prime requirement is the one that the apostle Paul stated to the Philippian jailer: “Believe on the Lord Jesus and you will get saved.” (Acts 16:31) Heartfelt acceptance of the shed blood of Jesus is essential if we are going to be saved.

Yes, believing in Jesus is crucial to our salvation, but more is needed. Jesus spoke of some who professed faith in him and even did “powerful works” in his name. But he did not recognize them. Why? Because they were “workers of lawlessness” and did not do the will of his Father. (Matthew 7:15-23) The disciple James reminds us of the need to “become doers of the word, and not hearers only, deceiving yourselves with false reasoning.” He also said: “You believe there is one God, do you? You are doing quite well. And yet the demons believe and shudder. . . . Faith without works is dead.”​—James 1:22; 2:19, 26.

Some, though, argue that those who are genuinely saved do all these things anyway. But is that really the case in practice? Denis, who ‘accepted Jesus’ when he was a young boy, says: “The ‘saved’ people I have known feel no great need to examine the Scriptures because they think they already have all they need for salvation.” Indeed, the hypocrisy and unchristian acts of many who claim to be saved have brought the whole subject of salvation into disrepute.

Nevertheless, many insist that the Scriptures say: “He that believeth on the Son hath everlasting life.” (John 3:36, King James Version) Therefore, they conclude that once you have accepted the Lord Jesus Christ as your personal Savior, you can never again be lost. “Once saved, always saved” is their watchword. But is that what the Scriptures really say? To answer this, we need to consider everything the Bible says on the subject. We would not want to ‘deceive ourselves with false reasoning’ by reading only selected parts of God’s Word.

“Once Saved, Always Saved”?

Notice the inspired warning of the disciple Jude. He wrote: “Beloved ones, though I was making every effort to write you about the salvation we hold in common, I found it necessary to write you to exhort you to put up a hard fight for the faith that was once for all time delivered to the holy ones.” (Jude 3) Why did Jude write this? Because he knew that individual Christians could still lose the ‘salvation they hold in common.’ He went on to say: “I desire to remind you . . . that Jehovah, although he saved a people [the Israelites] out of the land of Egypt, afterwards destroyed those not showing faith.”​—Jude 5.

Jude’s warning would be pointless if Christians did not face a danger similar to that of those Israelites. Jude was not questioning the value of Jesus’ sacrifice. That sacrifice has saved us from Adamic sin, and Jesus will protect those who exercise faith in him.
