A false feeling of invincibility

Jeremiah 5
v 12-15
They have lied about the Lord; they said, "He will do nothing! No harm will come to us; we will never see sword or famine. the prophets are but wind and the word is not in them; so let what they say be done to them."
Therefore this is what the Lord God Almighty says:
"Because the people have spoken these words, I will make my words in your mouth a fire and these people the wood it consumes..."

My life has been so fortunate that it is easy to think no harm will ever come to me. I have always been loved, clothed, and fed. I have had many opportunities, and have usually succeeded at them at least to a degree. My parents are proud of me and pleased with me. I get strokes from employers and coworkers, and in ministry at church. So I take all this positive feedback in -- and I put it next to the private and personal knowledge of my sin which is seldom noticed or mentioned -- and it starts to feel like I will never get 'caught' in my sin. No one knows my secret pride. No one knows my evil, hateful thoughts or lack of spiritual growth. I have my over-indulgences in food and fiction, and no one calls me on it. I have learned to apologize for my overt sins against others, and I am sincere and people usually forgive me.

Two things result from this:
1. I am prone to think, like Israel, God will do nothing. No harm will come to me.
2. At the same time, solitary awareness of my private sins, alongside my decent public image, make me all that much more prone to keep them private so as not to tarnish my image. I do not want to share these inner struggles or even admit them to myself, yet I feel shame over them. The longer I successfully hide, the harder it is to think that someone will 'find out who I really am' and their image of me will be shot to pieces.
3. When I do think about sharing my inner struggles, my evil and self-centered mind jumps to devising ways to share them that will also boost my public image -- i.e. "Isn't it wonderful how transparent she is? How much she wants to grow in the Lord?" -- and I imagine how much attention or respect I might get out of it.

I can understand why God cannot find any who deal honestly and seek the truth (v1) and why there is no basis in Israel or Judah's or my behavior on which to base forgiveness.

Any forgiveness given to me is entirely a result of God's merciful heart. I have no merit whatsoever.
