Agape,
But it is not by a person's mouth that he is saved.
Paul clearly shows a relation between "confessing with the mouth" and salvation. The verse clearly says "
with the mouth, confession is made unto
salvation. Paul goes on in verse 13 to say that "Whoever calls on the name of the Lord shall be saved." How do we "call" on the name of the Lord? Well, "
with the mouth, confession is made unto
salvation."
Paul himself called upon the name of the Lord in his conversion (Acts 22:16). By the way, he was baptized also. And if you notice, Jesus asked Paul "Why are you waiting, arise and be baptized...". Jesus told Paul to get baptized, which is proof that your theory of "a person is automatically baptized upon hearing the word" is not true. If Paul was automatically baptized, Jesus wouldn't have asked him why he was waiting.
Then there's the eunuch who wasn't baptized automatically as soon as he believed. When the eunuch acknowledged that he blieved in Jesus, Phillip took him down into the waters and baptized him. This happened AFTER he believed (not automatically) by Phillip, and it involved water.
All other verse "regarding salvation" simply tell us that we must do one thing, which is to believe in Jesus Christ.
Wrong:
Mark 16:16
16) He who believes and is baptized will be saved; but he who does not believe will be condemned.
1 Peter 3:21
21) There is also an antitype which now saves us-baptism (not the removal of the filth of the flesh, but the answer of a good conscience toward God), through the resurrection of Jesus Christ.
Acts 10:34-35
34) Then Peter opened his mouth and said: In truth I perceive that God shows no partiality.
35) But in every nation whoever fears Him and works righteousness is accepted by Him.
Romans 6:3-6
3) Or do you not know that as many of us as were baptized into Christ Jesus were baptized into His death?
4) Therefore we were buried with Him through baptism into death, that just as Christ was raised from the dead by the glory of the Father, even so we also should walk in newness of life.
5) For if we have been united together in the likeness of His death, certainly we also shall be in the likeness of His resurrection,
6) knowing this, that our old man was crucified with Him, that the body of sin might be done away with, that we should no longer be slaves of sin.
John 8:51
51) "Most assuredly, I say to you, if anyone keeps My word he shall never see death
Hebrews 5:9
9) And having been perfected, He became the author of eternal salvation to all who obey Him.
John 15:10
10) If you keep My commandments, you will abide in My love, just as I have kept My Father's commandments and abide in His love.
1 John 2:17
17) And the world is passing away, and the lust of it; but he who does the will of God abides forever.
1 John 3:24
24) Now he who keeps His commandments abides in Him, and He in him. And by this we know that He abides in us, by the Spirit whom He has given us.
Revelation 22:14
14) Blessed are those who do His commandments, that they may have the right to the tree of life, and my enter through the gates into the city.
1 John 2:3-4
3) Now by this we know that we know Him, if we keep His commandments.
4) He who says, "I know Him," and does not keep His commandments, is a liar, and the truth is not in him.
John 3:16: "For God so loved the world that He gave His only begotten Son, that whosoever BELIEVETH IN HIM shall not perish but have eternal life." This verse makes no mention of verbally confessing with the mouth.
1 John 2:4 makes it quite clear belief by itself won't do anybody any good. The "belief" spoken of in John 3:16 is the kind of belief that is acted upon. What good does it do you to hear the gospel and believe it, yet you don't
obey it? If one truly believes in Him, then they will obey His commandments.
There are many more verses which place the emphasis on "believing" in order to be saved.
I'm sure there are, but you just don't understand what kind of belief is being spoken of. It's not a dead belief unto it's own. The people who believed and converted where the ones who acted upon thier belief and
obeyed the gospel.
