It's More Than Just Knowing and Believing in God

To think that you can get into Heaven just by believing in Jesus is a lie. That is part of it yes, but there is more to it.
In Romans 1, Paul addresses some "believers" who know the Word and know God, but here is what he says about them starting in verse 18:
" For the wrath of God is revealed from heaven against ALL ungodliness and unrighteousness of men, who by their unrighteousness suppress the truth. For what can be known about God is plain to them, becuase God has SHOWN it to them. For His invisible attributes, namely, His eternal power and divine nature, have been clearly percieved, ever since the creation of the world, in the things that have been made. So they are WITHOUT EXCUSE.
For although they KNEW God, they did not honor Him as God or give thanks to Him, but they became futile in their thinking, and their foolish hearts were darkened. Claiming to be wise, they became fools, and exchanged the glory of the immortal God for images resembling mortal man and birds and animals and creeping things.
(I have a comment here. Are you putting anything in front of God in your life? Money? A person? Celebrities? Nothing should come before God in your life, "For where your treasure is, there your heart will be also." Matt 6:21)
Therefore, God gave them up in the lusts of their hearts to impurity, to the dishonoring of their bodies among themselves, because they exchanged the truth about God for a lie and worshipped and served the creature rather than the Creater, who is blessed forever! Amen.
For this reason, God gave them up to dishonorable passions. For their women exchanged natural relations for those that are contrary to nature; and the men likewise gave up natural relations with women and were consumed with passion for one another, men committing shameless acts with men and recieving in themselves the due penalty for their error.
And since they did not see fit to acknowledge God, God gave them up to a debased mind to do what ought not to be done. They were filled with all manner of unrighteousness, evil, covetousness, malice. They are full of envy, murder, strife, deciet, maliciousness. They are gossips, slanderers, haters of God, insolent, haughty, boastful, inventors of evil, disobedient to parents, foolish, faithless, heartless, ruthless. Though they know God's decree that those who practice such things deserve to die, they not only do them but give approval to those who practice them."

I'm just going to leave you with that. Think about it
