First, everyone is accountable as God has shown Himself in creation.
Romans 1:18-32(New American Standard Bible)
18For (
A)the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men who (
B)suppress the truth in unrighteousness,
19because (
C)that which is known about God is evident within them; for God made it evident to them.
20For (
D)since the creation of the world His invisible attributes, His eternal power and divine nature, have been clearly seen, (
E)being understood through what has been made, so that they are without excuse.
21For even though they knew God, they did not [
a]honor Him as God or give thanks, but they became (
F)futile in their speculations, and their foolish heart was darkened.
22(
G)Professing to be wise, they became fools,
23and (
H)exchanged the glory of the incorruptible God for an image in the form of corruptible man and of birds and four-footed animals and [
b]crawling creatures.
24Therefore (
I)God gave them over in the lusts of their hearts to impurity, so that their bodies would be (
J)dishonored among them.
25For they exchanged the truth of God for a (
K)lie, and worshiped and served the creature rather than the Creator, (
L)who is blessed forever. Amen.
26For this reason (
M)God gave them over to (
N)degrading passions; for their women exchanged the natural function for that which is unnatural,
27and in the same way also the men abandoned the natural function of the woman and burned in their desire toward one another, (
O)men with men committing indecent acts and receiving in their own persons the due penalty of their error.
28And just as they did not see fit to acknowledge God any longer, (
P)God gave them over to a depraved mind, to do those things which are not proper,
29being filled with all unrighteousness, wickedness, greed, evil; full of envy, murder, strife, deceit, malice; they are (
Q)gossips,
30slanderers, (
R)haters of God, insolent, arrogant, boastful, inventors of evil, (
S)disobedient to parents,
31without understanding, untrustworthy, (
T)unloving, unmerciful;
32and although they know the ordinance of God, that those who practice such things are worthy of (
U)death, they not only do the same, but also (
V)give hearty approval to those who practice them.
Second, there is only one true God - the Father, Son and Holy Spirit.
Isaiah 45:18-22(New American Standard Bible)
18For thus says the LORD, who (
A)created the heavens (He is the God who (
B)formed the earth and made it, He established it and did not create it a (
C)waste place, but formed it to be (
D)inhabited),
"I am the LORD, and (
E)there is none else.
19"(
F)I have not spoken in secret,
In some dark land;
I did not say to the (
G)offspring of Jacob,
'(
H)Seek Me in a waste place';
I, the LORD, (
I)speak righteousness,
(
J)Declaring things that are upright.
20"(
K)Gather yourselves and come;
Draw near together, you fugitives of the nations;
(
L)They have no knowledge,
Who (
M)carry about their wooden idol
And (
N)pray to a god who cannot save.
21"(
O)Declare and set forth your case;
Indeed, let them consult together
(
P)Who has announced this from of old?
Who has long since declared it?
Is it not I, the LORD?
And there is (
Q)no other God besides Me,
A righteous God and a (
R)Savior;
There is none except Me.
22"(
S)Turn to Me and (
T)be saved, all the ends of the earth;
For I am God, and there is no other.
Third, salvation is through Christ
Acts 4:1-12(New American Standard Bible)
Acts 4
Peter and John Arrested1As they were speaking to the people, the priests and (
A)the captain of the temple guard and (
B)the Sadducees (
C)came up to them,
2being greatly disturbed because they were teaching the people and proclaiming (
D)in Jesus the resurrection from the dead.
3And they laid hands on them and (
E)put them in jail until the next day, for it was already evening.
4But many of those who had heard the message believed; and (
F)the number of the men came to be about five thousand.
5On the next day, their (
G)rulers and elders and scribes were gathered together in Jerusalem;
6and (
H)Annas the high priest was there, and (
I)Caiaphas and John and Alexander, and all who were of high-priestly descent.
7When they had placed them in the center, they began to inquire, "By what power, or in what name, have you done this?"
8Then Peter, (
J)filled with the Holy Spirit, said to them, "(
K)Rulers and elders of the people,
9if we are on trial today for (
L)a benefit done to a sick man, as to how this man has been made well,
10let it be known to all of you and to all the people of Israel, that (
M)by the name of Jesus Christ the Nazarene, whom you crucified, whom (
N)God raised from the dead--by this name this man stands here before you in good health.
11"(
O)He is the (
P)STONE WHICH WAS (
Q)REJECTED by you, THE BUILDERS, but WHICH BECAME THE CHIEF CORNER stone.
12"And there is salvation in (
R)no one else; for there is no other name under heaven that has been given among men by which we must be saved."
Everyone will be judged by Christ. Those who are his will with with Him in Heaven for eternity. Those who are not His will spend eternity in Hell.
Hebrews 9:24-28(New American Standard Bible)
24For Christ (
A)did not enter a holy place made with hands, a mere copy of (
B)the true one, but into (
C)heaven itself, now (
D)to appear in the presence of God for us;
25nor was it that He would offer Himself often, as (
E)the high priest enters (
F)the holy place (
G)year by year with blood that is not his own.
26Otherwise, He would have needed to suffer often since (
H)the foundation of the world; but now (
I)once at (
J)the consummation of the ages He has been (
K)manifested to put away sin (
L)by the sacrifice of Himself.
27And inasmuch as (
M)it is appointed for men to die once and after this (
N)comes judgment,
28so Christ also, having been (
O)offered once to (
P)bear the sins of many, will appear (
Q)a second time for (
R)salvation (
S)without reference to sin, to those who (
T)eagerly await Him.
