What are Some Common Misconceptions when it Comes to the Gospel?
Misconception #1: You have to say a prayer to be saved.

Saying a prayer never saved anyone! It is our faith and trust in Jesus Christ that saves us. Saying a prayer is simply a way to verbally express to God the faith that we have in our hearts. There is no Biblical reference to Jesus ever leading anyone through a prayer for salvation. As a matter of fact, we don’t see any of the Christians in the New Testament ever leading someone else through a salvation prayer. It’s fine to lead someone through a simple prayer to God. Just make sure they understand that saying a prayer doesn’t save them. Their faith in Jesus saves them.
Misconception #2: You have to be water baptized to be saved.

Water baptism is an outward sign of an inward change. It is a picture of our new identity in Christ. Although there are a few verses that are misinterpreted by some that say it is necessary for salvation (Acts 2:38, Mark 16:16, etc.), there are over 200 verses in the New Testament that make it clear that salvation is a matter of faith alone in Christ alone. If baptism were necessary for salvation then it would have to appear as a requirement for salvation every single time the word “faith” or “believe” or “repent” does. As a matter of fact, in Acts 10:44-47 some people trust in Christ as a result of Peter’s preaching. Notice what he says in verse 47, “Can anyone keep these people from being baptized with water? They have received the Holy Spirit just as we have.” They received the Spirit before they were baptized. According to Ephesians 1:13 we receive the Spirit as soon as we believe. In other words, they were saved before they were ever water baptized.
Misconception #3: Eternal life is a license to sin.

The natural response to a free gift is gratefulness. The better and bigger the gift, the more grateful one tends to be. In the same way, when we are given the best gift ever, the gift of eternal life, our natural response should be a life of thankful service for God (Romans 12:1).

Yes, there are times when all of us have abused the grace of God and sinned. In the words of the great preacher, Dr. Martin Lloyd Jones,

“The true test of gospel preaching is whether or not it can be abused.”

Grace that cannot be taken advantage of is not grace. When we abuse God’s grace (and we all do from time-to-time), we miss out on the full blessing of God in our lives. We are cheating ourselves of present contentment in our earthly lives and future rewards in the heavenly life to come.
