Read the context
If we are confused by a certain Bible verse, it is a good idea to read its immediate context as well. Let’s do that together:“If you confess with your mouth that Jesus is Lord and believe in your heart that God raised him from the dead, you will be saved. For with the heart one believes and is justified, and with the mouth one confesses and is saved. For the Scripture says, ‘Everyone who believes in Him will not be put to shame.’ For there is no distinction between Jew and Greek; for the same Lord is Lord of all, bestowing His riches on all who call on Him. For ‘everyone who calls on the name of the Lord will be saved.’” (Romans 10:9-13)
This chapter says that people who hear the Gospel, should accept and believe it in order to be saved. The apostle Paul quotes various Bible verses to show that everyone who believes in God will be saved, regardless of his or her social, religious or racial background.Compare with other Bible verses
Another helpful step to take, is to compare a difficult Bible verse with other verses. The Bible will never contradict itself, so other verses can help us build a “framework” to fit the difficult verse in. In this case, some helpful verses are:- John 5:24, [Jesus said:] “Truly, truly, I say to you, whoever hears My word and believes Him who sent Me has eternal life. He does not come into judgment, but has passed from death to life.”
- Ephesians 2:8-9, “For by grace you have been saved through faith. And this is not your own doing; it is the gift of God, not a result of works, so that no one may boast.”
- Titus 3:5, “He saved us, not because of works done by us in righteousness, but according to His own mercy, by the washing of regeneration and renewal of the Holy Spirit.”
- Acts 16:30-31, [Someone asked the apostle Paul] “‘Sirs, what must I do to be saved?’ And they said, ‘Believe in the Lord Jesus, and you will be saved, you and your household.’”
Confessing that Jesus is Lord
Let’s read one more verse to understand better what is meant by “confessing with your mouth that Jesus is Lord”.“So everyone who acknowledges Me before men, I also will acknowledge before My Father who is in heaven, but whoever denies Me before men, I also will deny before my Father who is in heaven.” (Matthew 10:32-33)
Our words reveal what is in our heart. So if we confess Jesus with our mouth, this is an outward sign of our faith. It is important to do so, to witness to people around us about our faith, to honor God with it, and also because confessing and sharing our faith with others can strengthen us. Being a Christian while keeping totally silent is hardly possible. Matthew 10 mentions an alternative to confessing that Jesus is Lord, namely to deny Him. If we deny Jesus, this shows that we do not believe in Him. Then we cannot be saved! This is a totally different situation from the one described in the question, where someone does wholeheartedly believe in Jesus as his Lord and Savior but cannot confess this with his mouth.
