Yeah, if you believe that Jesus died and rose again to save you from your sins and you have asked Him to forgive you of your sins.. then you are saved eternally. And yeah.. that He is God.
That is Repentance.
Peter replied when asked in Acts 2:37 Now when they heard this, they were pricked in their heart, and said unto Peter and to the rest of the apostles, Men and brethren,
what shall we do?
Acts 2:38 Then Peter said unto them,
Repent, and be
baptized every one of you in the name of Jesus Christ
for the remission of sins, and ye shall receive the gift of the
Holy Ghost.
Romans 10:
(Rom 10:8) But what saith it? The word is nigh thee, even in thy mouth, and in thy heart: that is, the word of faith, which we preach;
(Rom 10:9) That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved.
(Rom 10:10) For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation.
(Rom 10:11) For the scripture saith, Whosoever believeth on him shall not be ashamed.
(Rom 10:12) For there is no difference between the Jew and the Greek: for the same Lord over all is rich unto all that call upon him.
(Rom 10:13) For whosoever shall call upon the name of the Lord shall be saved.
Lets read the very next verse...
Romans 10:13 For whosoever shall call upon the name of the Lord shall be saved.
[14]
How then shall they call on him in whom they have not believed? and how shall they believe in him of whom they have not heard? and how shall they hear without a
preacher?
[15] And how shall they preach, except they be
sent? as it is written, How beautiful are the feet of them that preach the gospel of peace, and bring glad tidings of good things!
Lets turn to the book of Acts for a moment...
Acts 8:26 And the angel of the Lord spake unto Philip, saying, Arise, and go toward the south unto the way that goeth down from Jerusalem unto Gaza, which is desert.
[27] And he arose and went: and, behold, a man of Ethiopia, an eunuch of great authority under Candace queen of the Ethiopians, who had the charge of all her treasure, and had come to Jerusalem for to worship,
[30] And Philip ran thither to him, and heard him read the prophet Esaias, and said, Understandest thou what thou readest?
[31] And he said, How can I, except some man should guide me? And he desired Philip that he would come up and sit with him.
[32] The place of the scripture which he read was this, He was led as a sheep to the slaughter; and like a lamb dumb before his shearer, so opened he not his mouth:
[33] In his humiliation his judgment was taken away: and who shall declare his generation? for his life is taken from the earth.
[34] And the eunuch answered Philip, and said, I pray thee, of whom speaketh the prophet this? of himself, or of some other man?
Now this is where I'm going with this...
Acts 8:35 Then Philip opened his mouth, and began at the same scripture, and
preached unto him Jesus.
[36] And as they went on their way, they came unto a certain
water: and the eunuch said, See, here is water; what doth hinder me to be
baptized?
In the PREACHING of JESUS we see that Water Baptism was preached, which is in accordance with Peter's reply in Acts 2:38. And preaching water baptism is the burial with Christ...
Romans 6:3 Know ye not, that so many of us as were baptized into Jesus Christ were baptized into his death?
[4] Therefore we are
buried with him by baptism into death: that like as Christ was raised up from the dead by the glory of the Father, even so we also should walk in newness of life.
And, when someone asks how to be saved, we preach unto them Jesus and Acts 2:38, just as Peter had done.
-Thank you.
