It is not particular sins that send someone to hell it is their sinful nature that can only be changed by Christ when they trust in Him.
Proverbs 3:5-6
"5 Trust in the Lord with all your heart
And do not lean on your own understanding.
6 In all your ways acknowledge Him,
And He will make your paths straight."
We cannot make our own path straight by trying to be good. It is only Christ Who is good.
He changes us into a new creation when we trust Christ. We no longer think the way we used to think as a sinful man tainted by worldly emotions.
Jeremiah 17:7-8
"But blessed is the man who trusts in the LORD, whose confidence is in Him. / He is like a tree planted by the waters that sends out its roots toward the stream. It does not fear when the heat comes, and its leaves are always green. It does not worry in a year of drought, nor does it cease to produce fruit."
Psalm 37:3-5
"Trust in the LORD and do good; dwell in the land and cultivate faithfulness. / Delight yourself in the LORD, and He will give you the desires of your heart. / Commit your way to the LORD; trust in Him, and He will do it."
Isaiah 26:3-4
"You will keep in perfect peace the steadfast of mind, because he trusts in You. / Trust in the LORD forever, because GOD the LORD is the Rock eternal."
Those who are driven by emotions are not trusting in Christ, they are depending entirely on themselves falsely believing that they deserve what they want the way they want it.
Philippians 4:6-7
"Be anxious for nothing, but in everything, by prayer and petition, with thanksgiving, present your requests to God. / And the peace of God, which surpasses all understanding, will guard your hearts and your minds in Christ Jesus."
What a blessing it is to know that Christ does all the work in us, redirecting us when we stray from truth and blessing us with wisdom when we ask for it.
James 1:4-6 "…4 Allow perseverance to finish its work, so that you may be mature and complete, not lacking anything. 5 Now if any of you lacks wisdom, he should ask God, who gives generously to all without finding fault, and it will be given to him. 6 But he must ask in faith, without doubting, because he who doubts is like a wave of the sea, blown and tossed by the wind.…"
There is no excuse for the born-again believer to not understand the truth in God's Word. God said clearly that all we have to do is ask Him and He will not disappoint. However, we must admit we don't know everything and that He does know everything, submitting to Him when He speaks.
