The Scriptures clearly show that we are saved by faith in Jesus Christ, apart from all works.
The Bible does not classify a sinner’s prayer, repentance, confessing Jesus, hearing and reading God’s Word, and water baptism as a form of works. Water baptism is a command to fulfill all righteousness, and as the answer of a good conscience toward God by the resurrection of Jesus Christ.
Biblical baptism is to be done by full immersion in the name of the Father, and of the Son, and of the Holy Ghost. In the Bible, water baptism, confessing one’s sins, and calling on the name of the Lord were interwoven in Mt 3:6 and Acts 22:16.
Sprinkling baptism and infant baptism are counterfeits. They are actually no baptism at all.
Water baptism is a commandment; however, water baptism before a person repents and before a person believes with all their heart on Jesus, is no baptism at all. Water baptism comes as a result of repenting and believing on Jesus. If a person went into adultery, fornication, any sex outside of marriage, or total rebellion against God after water baptism; it may be a good indication that true repentance before water baptism was false. Thus, the water baptism meant nothing.

Some people may want to be baptized just for the sake of being baptized; yet there is no evidence of repentance or saving knowledge of Jesus from God’s Word in the person to produce faith. This is not biblical. The baptism has no meaning.
A person is not to be baptized, if they do not believe on Jesus with all their heart and repent first.
The Bible clearly shows that a person does reject God’s Word (or Jesus), if they are not baptized.
The Scriptures clearly indicate that a person may be born-again when they come up out of the water, if they truly believe on Jesus with all their heart and have repented. They come out into the newness of life.
The Scriptures appear to show that a person receives the Holy Ghost upon coming out of the water of baptism, but only if believing and repentance precede baptism.
The Bible also tells us that baptism doth also now save us (not the putting away of the filth of the flesh, but the answer of a good conscience toward God,) by the resurrection of Jesus Christ.
And we are told, THERE ARE THREE THAT BEAR WITNESS IN EARTH, THE SPIRIT, AND THE WATER, AND THE BLOOD: AND THESE THREE AGREE IN ONE.
The Bible also gives us very clear indications regarding water baptism: when it can and if it should be done again.
And finally, it is written, in Gal 3:27-FOR AS MANY OF YOU AS HAVE BEEN BAPTIZED INTO CHRIST HAVE PUT ON CHRIST. How do we put on Christ? Note, it does not say baptized, but baptized "into Christ."

The word "apologetics" comes from the Greek word "apologia," pronounced, "ap-ol-og-ee’-ah." It means, "a verbal defense." It is used eight times in the New Testament: Acts 22:1; 25:16; 1 Cor. 9:3; 2 Cor. 7:11; Phil. 1;7,17; 2 Tim. 4:16, and 1 Pet. 3:15. But it is the last verse that is most commonly associated with Christian apologetics.

"but sanctify Christ as Lord in your hearts, always being ready to make a defense to everyone who asks you to give an account for the hope that is in you, yet with gentleness and reverence"
(1 Pet. 3:15, NASB).

Therefore, Christian apologetics is that branch of Christianity that deals with answering any and all critics who oppose or question the revelation of God in Christ and the Bible. It can include studying such subjects as biblical manuscript transmission, philosophy, biology, mathematics, evolution, and logic. But it can also consist of simply giving an answer to a question about Jesus or a Bible passage. The later case is by far the most common and you don’t have to read a ton of books to do that.
Apologetics can be defensive and offensive. Phil. 1:7 gives us instruction on the defensive side, “For it is only right for me to feel this way about you all, because I have you in my heart, since both in my ²imprisonment and in the defense and confirmation of the gospel, you all are partakers of grace with me.” 2 Cor. 10:15-6 gives us instruction on the aggressive side, “We are destroying speculations and every lofty thing raised up against the knowledge of God, and we are taking every thought captive to the obedience of Christ.” The apologist can and should defend his reasons for believing (1 Pet. 3:15). But, he can also go on the attack. He can seek out those who oppose Christianity (2 Cor. 10:5). Of course, he should be prepared to do this before hand and all apologetics is to be done with gentleness.
Apologetics is the work of convincing people to change their views. In this it is similar to preaching because its goal is ultimately the defense and presentation of the validity and necessity of the gospel. It is an attempt to persuade the listener to change his beliefs and life to conformity to biblical truth and to come to a saving relationship in Christ.f
Apologetics can be, basically, evidential (often called "classical") or presuppositional. Evidential apologetics deals with the evidence for Christianity: Jesus’ resurrection, the biblical manuscripts, fulfilled prophecy, miracles, etc. Presuppositional apologetics deals with the presuppositions of those who oppose Christianity, because presuppositions effect how a person views evidence and reason.
Some areas of debate within Christian apologetics deal with the use of evidence, reasons, philosophy, etc. Should the apologist use only those criteria acceptable to unbelievers? Are we allowed to use the Bible as a defense of our position or must we prove Christianity without it? Is reason alone sufficient to prove God existence or Christianity’s truth? How much should reason and evidence be used in light of the Scriptures teaching that it is God who opens the mind to understand? What part does prayer, using the Bible, and the sinful nature of the unbeliever play in witnessing? How do these factors interrelate to bring an unbeliever to faith? The questions are easy. The answers are not.
Jesus chose one highly educated religious person as an apostle. That was Paul. The rest were fishermen, a tax collector, a doctor, etc. They were normal people of the day who were available and willing to be used by the Lord. They were filled with the Spirit of God and they were used as vessels of God. God uses all things for His glory. So, we do apologetics by faith.
The Lord has called every Christian to be ready to make a defense of his faith. That means you are called to give reasonable answers to questions regarding Christianity. Now, this does not mean that you must have a Ph.D or that you have to go to seminary. But it does mean that you should be willing to at least give an answer for your beliefs. If you find you cannot, then prayerfully take it to God and start studying.

What do you study?

You could pray and ask the Lord to teach you what He wants you to know. Ask Him to give you a burden for something to learn. It doesn’t matter what it is. Just ask. Whatever you become interested in is what you should learn about because it is probably something God wants you to know for later use. It is like having tools in a tool shed. The more you have, the more you can accomplish.
Another way to find out what God wants you to study through circumstances. Let’s say that a Jehovah’s Witness comes to your door and debates the deity of Christ with you and you find you don’t know how to defend it biblically. In that case, you know you need to study biblical verses that teach Jesus is God in flesh. Or maybe a coworker asks you how you know the Bible is true? If you don’t have a answer, pray, and start researching. Go to a Christian bookstore and get some books on it. Talk to your pastor. You’ll learn.
Sometimes God will make a verse or subject in the Bible "come alive" to you and it might strike you as odd or interesting. You could get a commentary and read up on it. You could ask others about it. In so doing, you are preparing yourself through learning to be ready to answer questions and point people to the truth. You'd be surprised how many details God can use to help you in your witness, even through those apparently odd times when verses suddenly "come alive."

Get An Ignorance Notebook

The ignorance notebook is something I started almost 20 years ago to help me study. You can make one yourself. It’s simple. Get a 3 ring binder and fill with blank pages. Then ask God to fill it with what you need to know.
As in the examples above, God will put burdens on your heart, or cause you to find places where you are lacking in knowledge, or a Bible verse will strike you. Write down what you learn in your notebook. Date the pages as you go. You’ll be amazed at what you learn.
Basically, apologetics is equivalent to theology in sneakers. It means getting the hay down off the loft and down to where the cows can eat it. Anyone can ‘do’ apologetics. All it takes is a willingness, a little work, and the Spirit of God in you.
