“Son of man, these leaders have set up idols in their hearts. 
They have embraced things that will make them fall into sin. 
Why should I listen to their requests
- Ezekiel 14:3 (New Living Translation)

...these men have set up their idols in their hearts,
and put before them that which causes them to stumble into inquity.
- Ezekiel 14:3 (New King James Version)

Simply feeling sad is not necessarily an indication that we have done wrong or that we are outside God's will. Verify your feelings in the light of what the Word of God says...

Abstain from all appearance of evil.
- 1 Thessalonians 5:22

Don’t you realize that this sin is like a little yeast that spreads through the whole batch of dough?
- 1 Corinthians 5:6

For the Lord grants wisdom!
From his mouth come knowledge and understanding.
He grants a treasure of common sense to the honest.
He is a shield to those who walk with integrity.
He guards the paths of the just
and protects those who are faithful to him.
- Proverbs 2:6-8

I called on Your name, O LORD,
From the lowest pit
You have heard my voice:
"Do not hide Your ear
From my sighing, from my cry for help"
You drew near on the day I called on You
And said, "Do not fear!"
- Lamentations 3:55-57

Therefore, if anyone is in Christ, he is a new creation; old things have passed away; behold, all things have become new
- 2 Corinth 5:17

...Christ made us right with God; he made us pure and holy, and he freed us from sin.
- 1 Corinthians 1:30

You can't earn God's love by being good enough, so stop your performance. You are justified through faith in God, not through righteous performance for God.

Therefore, since we have been justified through faith, we have peace with God through our Lord Jesus Christ.
- Rom 5:1
