Christ commanded His disciples to baptize those whom God called to repentance: “Go therefore and make disciples of all the nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all things that I have commanded you; and lo, I am with you always, even to the end of the age” (Matthew 28:19–20).

What makes a baptism valid in God’s eyes? Surely Jesus Christ knows, as it was He who established the requirement of baptism for salvation: “And He said to them, ‘Go into all the world and preach the gospel to every creature. He who believes and is baptized will be saved; but he who does not believe will be condemned’” (Mark 16:15–16).

What must one believe? One must believe the Gospel Jesus preached. What was that Gospel? “Jesus came to Galilee, preaching the gospel of the kingdom of God, and saying, ‘The time is fulfilled, and the kingdom [government] of God is at hand. Repent, and believe in the gospel’” (Mark 1:14–15).

Jesus Christ, the Son of God, brought the good news that God’s kingdom will ultimately take control of all the world’s governments, administering a time of peace between formerly warring nations.

Of what must one repent? Of sin—so, what is sin? “Whosoever commits sin transgresses also the law: for sin is the transgression of the law” (1 John 3:4, JUB). At your baptism, did you obey Jesus’ instruction to repent of transgressing the Ten Commandments (Matthew 19:17–19)?

Keeping these points in mind, you can ask yourself this question: When you were baptized, did you truly repent of your sins? If you knew what sin is, but did not resolve to turn utterly and completely away from it with the help of your Savior, you did not truly repent. And if you did not even know what sin is (perhaps you believed that as a Christian you could do whatever you wanted and not have it counted as sin) you certainly did not repent of your sins.

One sign of an invalid baptism is that it did not follow the scriptural example. Notice that Scripture clearly instructs that baptisms are to be performed by fully immersing someone in water (Matthew 3:13–16; John 3:23; Acts 8:38–39). A mere sprinkling does not adhere to the biblical symbolism of washing away past sins (Acts 22:16).

Additionally, if you were baptized at a very young age—perhaps even baptized as an infant—you could not have comprehended what it means to repent. If you were not even the one who requested your own baptism, this is a sure sign that it did not signal your true repentance. Ultimately, repentance and baptism are willing commitments of the person being baptized!

Perhaps you feel that you did repent when you were baptized. If so, ask yourself another question: Did you believe the true Gospel? Today, most people who call themselves “Christians” have a hazy and incorrect idea of the Gospel. Some think of it as a message about Jesus, while others think of it as a message about prosperity or self-affirmation. Few understand the truth—that the Gospel Jesus preached was the Gospel of the Kingdom of God, the message of a soon-coming kingdom ruled by Jesus Christ Himself, under which all of humanity will experience the joys and blessings of living God’s way.

Some people rush into baptism because they think it is the socially acceptable thing to do—perhaps because their friends have all been baptized and they feel left out. As a result, they may seek baptism long before they have truly “counted the cost” of this eternal commitment (Luke 14:28). Because baptism is such a weighty decision, you should be wary of those who want to hurry you into baptism without allowing you time to pray, study, and fast as you seek God’s will for your life.
