  • The Bible clearly teaches that there is only one true God and all other gods are false idols.
  • God forbids mixing of other religions with the worship of Him.

With that foundation, let’s dive into this important topic and see what God wants us to know.

What Does the Bible Say About Different Religions?

There Is Only One True God

A foundational teaching throughout Scripture is that there is only one true God who created all things and deserves our worship. The very first of the Ten Commandments states:

“I am the Lord your God, who brought you out of the land of Egypt, out of the house of bondage. You shall have no other gods before Me.” (Exodus 20:2-3 NKJV)

This commandment establishes that the God who led Israel out of slavery is the one true God. No other so-called deities are to be worshipped or revered. God alone is the supreme being worthy of praise.

The Bible repeats this truth many times:

“Therefore know this day, and consider it in your heart, that the Lord Himself is God in heaven above and on the earth beneath; there is no other.” (Deuteronomy 4:39 NKJV)

“Thus says the Lord, the King of Israel, And his Redeemer, the Lord of hosts: ‘I am the First and I am the Last; Besides Me there is no God.” (Isaiah 44:6 NKJV)

“I am the Lord, and there is no other; There is no God besides Me.” (Isaiah 45:5 NKJV)

These verses leave no room for debate: the God of the Bible is the one and only true God. This rules out all other deities devised by human religions. Yahweh alone is Almighty God.

God Forbids Mixing Other Religions with Worship of Him

Not only is the God of the Bible unique, but He forbids worshipping Him alongside other gods or integrating foreign religious practices into the worship of Him.

For example, the Israelites were strongly warned against adopting the pagan customs of surrounding nations:

“When the Lord your God cuts off from before you the nations which you go to dispossess, and you displace them and dwell in their land, take heed to yourself that you are not ensnared to follow them…that you do not inquire after their gods, saying, ‘How did these nations serve their gods? I also will do likewise.’ You shall not worship the Lord your God in that way; for every abomination to the Lord which He hates they have done to their gods.” (Deuteronomy 12:29-31 NKJV)

God wanted His people to avoid mingling elements of counterfeit religions into the pure worship He prescribed. The pagan nations were following false gods and twisted religious systems. God did not want His people tainting their worship of Him with those unholy influences.

In 2 Kings 17, God punishes Israel for its idolatry in adopting the practices of pagan nations and serving other gods. The chapter concludes:

“They rejected His statutes and His covenant that He had made with their fathers, and His testimonies which He had testified against them; they followed idols…So these nations feared the Lord, yet served their carved images; also their children and their children’s children have continued doing as their fathers did, even to this day.” (2 Kings 17:15, 41 NKJV)

Integrating other religions into the worship of God was strictly forbidden. God desires set-apart devotion to Him alone.

Salvation Is Only Through Christ, Not Man-Made Religion

The Bible clearly states that salvation is accessed through faith in Jesus Christ alone. No other religion or philosophy leads to salvation.

Jesus Himself said: “I am the way, the truth, and the life. No one comes to the Father except through Me.” (John 14:6 NKJV)

The apostles echoed this truth:

“Nor is there salvation in any other, for there is no other name under heaven given among men by which we must be saved.” (Acts 4:12 NKJV)

“For there is one God and one Mediator between God and men, the Man Christ Jesus, who gave Himself a ransom for all.” (1 Timothy 2:5-6 NKJV)

All religions that deny Jesus as the only Savior are false paths. Biblical Christianity is the only true faith and way to God.

The book of Acts records how the apostles preached this singular way of salvation to diverse religious groups:

“Then Paul stood in the midst of the Areopagus and said…’God, who made the world and everything in it, since He is Lord of heaven and earth…has appointed a day on which He will judge the world in righteousness by the Man whom He has ordained. He has given assurance of this to all by raising Him from the dead.’” (Acts 17:22, 30-31 NKJV)

Paul confronted Greek philosophers and called them to repent and believe in the resurrected Jesus for salvation. Man’s wisdom apart from Christ is insufficient for redemption.

False Religions Rely on Human Wisdom, Not God’s Truth

A distinguishing characteristic of false religions is that they rely on human wisdom rather than divine revelation. Their belief systems were created by human thinkers, not imparted by God.

The Bible warns of philosophy and tradition not aligned with Christ:

“Beware lest anyone cheat you through philosophy and empty deceit, according to the tradition of men, according to the basic principles of the world, and not according to Christ.” (Colossians 2:8 NKJV)

In one of His rebukes of the Pharisees, Jesus pointed out how they used man-made rules to negate God’s Word:

“He answered and said to them, ‘Well did Isaiah prophesy of you hypocrites, as it is written: ‘This people honors Me with their lips, But their heart is far from Me. And in vain they worship Me, Teaching as doctrines the commandments of men.’ For laying aside the commandment of God, you hold the tradition of men.” (Mark 7:6-8 NKJV)

False religions exalt human tradition over divine truth. Their practices are rooted in man’s reasoning rather than God’s perfect revelation.

We Must Test All Teachings Against Scripture

How can we as believers avoid being deceived by counterfeit religions and cults? By testing all teachings against Scripture.

The apostle John gave this warning:

“Beloved, do not believe every spirit, but test the spirits, whether they are of God; because many false prophets have gone out into the world.” (1 John 4:1 NKJV)

And Paul commended the Bereans for examining his own teachings against the Word of God:

“Then the brethren immediately sent Paul and Silas away by night to Berea. When they arrived, they went into the synagogue of the Jews. These were more fair-minded than those in Thessalonica, in that they received the word with all readiness, and searched the Scriptures daily to find out whether these things were so.” (Acts 17:10-11 NKJV)

Anything contrary to the Bible must be rejected. Scripture is our standard for evaluating all doctrines and philosophies.

God Calls Us Out of False Religion

Not only does Scripture renounce counterfeit religions as unable to save, but it declares God’s power to deliver people out of them into true faith:

“For He has delivered us from the power of darkness, and conveyed us into the kingdom of the Son of His love, in whom we have redemption through His blood, the forgiveness of sins.” (Colossians 1:13-14 NKJV)

“For you were once darkness, but now you are light in the Lord. Walk as children of light.” (Ephesians 5:8 NKJV)

“But God be thanked that though you were slaves of sin, yet you obeyed from the heart that form of doctrine to which you were delivered.” (Romans 6:17 NKJV)

No false religion has a hold on us that God cannot break. His grace enables repentant sinners to forsake old beliefs and embrace new life in Christ.


The testimony of Scripture about false religions is clear. There is only one God worthy of worship. All other gods are merely idols. Jesus Christ is the singular Savior of the world. All belief systems apart from Him can never reconcile us to God.

As believers, we must be vigilant to test all spiritual teachings against the Word of God. And we must place our faith in Christ alone for salvation. Jesus urged His followers:

“Behold, I send you out as sheep in the midst of wolves. Therefore be wise as serpents and harmless as doves.” (Matthew 10:16 NKJV)

May we interpret all religions and philosophies through the lens of God’s revealed truth. And may Christ be glorified as the only way to the Father.
