God hates those who lie to Him. That is why He said that liars cannot enter heaven.

Revelation 22:15 Outside are the dogs, those who practice magic arts, the sexually immoral, the murderers, the idolaters and everyone who loves and practices falsehood.

Who specifically does God refer to as liars? Those who do not keep God's commandments are liars.

Keeping God's commandments is an expression of faith that shows through actions that one believes in God who commanded one to keep those commandments. However, today many people who claim to believe in God do not keep the commandments, saying they have been abolished. Yet they claim that they love God and know God well. God is advocating that those who act like this are liars.

1 John 2:3-6 We know that we have come to know him if we keep his commands. Whoever says, “I know him,” but he does not do what he commands is a liar, and the truth is not in that person. But if anyone obeys his word, love for God is truly made complete in them. This is how we know we are in him: Whoever claims to live in him must live as Jesus did.

The Bible says that those who say they know God but do not keep God’s commandments are liars and do not have the truth. Therefore, no matter how much those who do not keep God's commandments emphasize their faith in God, they are just liars who cannot enter heaven.

Let us be true to God. If he wants to enter the kingdom of heaven prepared by God, he must faithfully keep God's commandments.
