Two scriptures indicating that we must believe on Christ are Acts 16:31 Acts 16:31And they said, Believe on the Lord Jesus Christ, and you shall be saved, and your house.
American King James Version×and Romans 10:9 Romans 10:9That if you shall confess with your mouth the Lord Jesus, and shall believe in your heart that God has raised him from the dead, you shall be saved.
American King James Version×. The former says, “So they said, ‘Believe on the Lord Jesus Christ, and you will be saved, you and your household,'” and Romans 10:9 Romans 10:9That if you shall confess with your mouth the Lord Jesus, and shall believe in your heart that God has raised him from the dead, you shall be saved.
American King James Version×says, “If you confess with your mouth the Lord Jesus and believe in your heart that God has raised Him from the dead, you will be saved.”
To properly understand these scriptures, we must know what it means to believe. Some people minimize the word believe by defining it as simply knowing Christ exists when it really means trusting Him and living one's life to please Him. Vine's Expository Dictionary of Biblical Words explains that the Greek word pisteuo (the Greek word found in both passages) means “'to believe,' also 'to be persuaded of,' and hence, 'to place confidence in, to trust,' signifies, in this sense of the word, reliance upon, not mere credence.”
There is obviously more to receiving salvation than simply knowing Christ lived. While we cannot earn our salvation through good works because salvation is a gift from God (Romans 6:23 Romans 6:23For the wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord.

American King James Version×; Revelation 14:12 Revelation 14:12Here is the patience of the saints: here are they that keep the commandments of God, and the faith of Jesus.

Those who truly love God will do these things because they have dedicated their lives to Him (Galatians 2:20 Galatians 2:20I am crucified with Christ: nevertheless I live; yet not I, but Christ lives in me: and the life which I now live in the flesh I live by the faith of the Son of God, who loved me, and gave himself for me.
