Is it true that I must repent and be baptized to be saved today?

Someone's comment given from this post 

The scriptures do not say accept the Lord Jesus as your Savior and ye shall be saved but it does say in Acts 2:38,39 and other places in Acts to repent and be baptized in the name of Jesus for the remission of sins and you shall receive the gift of the Holy Ghost. Notice you have to first repent.

The requirements for salvation you refer to in Acts 2 are the requirements of the Kingdom gospel which is relevant for the Jews during that dispensation. Today, in the grace dispensation, the requirement for salvation is to hear and chose to believe in the grace gospel of the cross work of Jesus Christ. In the grace gospel, salvation is not tied up in confessing Jesus Christ as the Messiah and Son of God. It is also not in the requirement of water baptism which is an ordinance necessary in the Jewish program. It is believing that the death of Jesus Christ is for the forgiveness of sins and that His resurrection is for our justification and right standing before God.

In a sense, you are absolutely right that the gospel is not about accepting the Lord Jesus as your Savior in order to be saved. Unfortunately, this, like the other things mentioned below are misconceptions about 'how to be saved'.

Things like:

1. Invite Jesus into your heart.
2. You must walk the aisle and confess your sins in front of witnesses.
3. You must be water baptized to qualify for salvation.
4. Say the sinners' prayer

All these above are man-made traditions that can be dangerously misleading if that person has not first heard the presentation of the grace gospel and then chose to respond to that message when God works that moment of faith in their heart.

What is the gospel message?

That Jesus Christ died for the sins you committed and by His blood payment on the cross He redeemed you from the penalty of death. That by the resurrection of Christ from the dead, you are justified before God and are sealed by the Holy Spirit into the body of Christ. See 1 Cor.15:1-4 and Eph.2:8-9

Only the gospel message contains the power to bring someone to salvation. (Rom.1:16). Nobody can coerce or force anybody to be saved. Salvation comes when God produces that moment of faith in a person's heart to believe the gospel message (see Acts 16:14; 1 Corinthians 1:30; Ephesians 1:18; Galatians 1:15-16; Titus 3:5). If that person choses to respond to that faith and believes that the cross work of Jesus Christ is their only way to be saved, then they will experience salvation in that instant, and they are regenerated in spirit and made alive into a new creation.

Salvation cannot be coerced. It cannot be earned. It cannot be forced upon another. It cannot be bought. Salvation is a personal experience between God and the person who has heard the gospel and is responding to it by faith in Christ alone.

Finally, the gospel will inevitably transform the life of a believer. Christianity is about regeneration, not reformation. Our lives are not changed by changing our character, but our character is changed by a change of life; by reading the Word and walking in willing obedience to the indwelling Spirit of Life.

Read again in Acts starting in Acts 2:38,39 Peter commanded the Jews to be baptized in the name of Jesus. Peter also commanded the gentiles in Acts 10 to be baptized in the name of Jesus. Do you know what the word "commanded" means?

Peter is one of the Jewish apostles who operates under the prophetic program and under the law. Peter is not the apostle of the body of Christ and although he is giving a command in those verses, it is to those under the prophetic program and not to us.

On the other side of the coin, Paul is our apostle, the apostle of the gentiles. We need to heed to what Paul writes which are instructions to the church under grace today. Paul is also the one who wrote that we need to rightly divide the word and separate that which is for Israel from that which is for the body of Christ under grace. It iso important that one does not mix or blend scripture together from the two separate dispensations, else one ends up with a skewed interpretation of doctrine.

There is only one plan of salvation in the New Testament and that is Acts 2:38,39. Ignore this at your soul's peril. You forget Peter had the KEY TO HEAVEN. And he used that key in Acts 2:38,39. Peter also commanded the gentiles to obey Acts 2:38,39. The same plan of salvation for the Jews and Gentiles in the New Testament.

You have the Kingdom gospel spot on. I have written many blog posts to document the kingdom gospel, but the part you are overlooking is that there is not just one gospel.

There is the gospel of the kingdom (for the Jews, to inherit the earth [Millennial Kingdom]) and there is the gospel of the grace of God (for the Gentiles, to inherit the heavens). The kingdom gospel is about identifying Jesus as the Messiah, confessing His name, being baptized and enduring faithfully to the end in works. This is not the conditions Paul specifies for the body of Christ. The grace gospel is about the cross work of Christ. It is about His death for our forgiveness and His resurrection for our justification. The grace gospel does not include the requirements of confession, repentance, and water baptism. The writings of Paul are pretty clear on this. “Not of works, so that nobody can boast!”

Here is a post I wrote with some clarifying answers regarding the gospels:

I’m certainly not ignoring anything regarding the critical doctrine of salvation. I have done extensive studies in my writings on this topic. The scriptures are very clear about the transitions between the gospel of the kingdom and the grace gospel. I stand in confidence in my understanding of it. If the gospel did not change between the Jews and the Gentiles, why did God need Paul? What then was the purpose of his ministry to the Gentiles?
