Of course every sin can lead you to hell but according to the bible, there is a sin which is more dangerous than others.
One of God’s purposes in creating Union was for our pleasure. But God also set limits on its enjoyment for our protection. According to the Bible, when we stray outside those protective boundaries, we sin against him
1 Corinthians 6: 17-19
17 But he who joins himself to the Lord becomes spiritually one with him. 18 Avoid immorality. Any other sin a man commits does not affect his body; but the man who is guilty of sexual immorality sins against his own body. 19 Don’t you know that your body is the temple of the Holy Spirit, who lives in you and who was given to you by God? You do not belong to yourselves but to God.
The bible is very clear all other sins a man commits are outside his body but the sin immorality is against one’s own body which is temple of the Holy spirit.
Please brethren lets abstain ourselves from evil desires of flesh and seek righteousness .
