There are several ingredients that are necessary in order to become saved. Let's explore what the Bible says you need to do to be saved.
The Bible states that you must hear the word first. In John 5:24, it says, "Truly truly I say to you, he who hears My word, and believes him who sent Me has eternal life."
One needs to then understand what he hears. It is not merely enough to just hear. In the same verse, John 5:24, it states that belief is necessary to become saved.
When the people who crucified Jesus asked Peter and the apostles in Acts 2:38 what must they do to be saved, they were instructed to Repent. Repentance means to change your mind, change your course, make an about face. Again, in Acts 17:30, Paul states that "God is now declaring to me that all people everywhere should repent."
In Romans 10:9, it states that "If you confess with your mouth Jesus as Lord, and believe in your heart that God raised Him from teh dead, you will be saved. In Matthew 10:32, it states that "Everyone who confesses Me before men, I will also confess him before my Father in heaven.
The people who crucified Christ in Acts 2:38 were told to: "Repent, and each of you be baptized in the name of Jesus Christ for the forgiveness of your sins; and you will receive the gift of the Holy Spirit." After this, in Acts 2:41, we are told of the great news, that "Those who received his word were baptized; and that day were added about three thousand souls.
1 Peter 3:21 says plainly, "Baptism now saves you."
The answer is no. Let's look at some examples from the Bible on how one becomes saved:
1. Ethiopian Eunuch- Acts 8:25-39. In verse 35, Philip is preaching to the eunuch. The eunuch is hearing. In verse 37, Philip says, "If you believe with all your heart, you may (be baptized). And he answered and said, "I believe that Jesus Christ is the son of God. Here we have the eunuch believing and confessing Jesus Christ as his Lord. He does not stop here though. In verse 38, the chariot was ordered to stop; "and they both went down into the water, Philip as well as the eunuch, and he baptized him."
2. Lydia- Acts 16:14. In verse 14, Lydia is listening to God's word. In verse 15, she was baptized. So here we see only listening and baptism mentioned in her conversion
3. The Jailer- Acts 16:30-40. In verse 30, the jailer asks the question of Paul and Silas, "Sirs, what must I do to be saved?" In verse 31, they answer, "Believe in the Lord Jesus and you will be saved, you and your household. And they spoke the word of the Lord to him together with all who were in his house. And he took them that very hour of the night and washed their wounds, and immediately he was baptized, he and all his household." In this instance of conversion, these people heard, believed, and were baptized.
Every time someone is converted in the Bible, it does not list all of the above ingredients every time. Yet, if we take a combination of conversions in the Bible, we can find the above equation.
