Since God sees me, I will stop trying to hide (Jer 16:16-18, Psalm 32:5)

My eyes are on all their ways; they are not hidden from me, nor is their sin (iniquity) concealed from my eyes. Jer 16:17

Interpretation for verse 18) "double payment for sin" see also Rev 18:6, "Give back to her as she has done to others; pay her back double for what she has done; mix her a double portion in her own cup."

• wickedness/sins/iniquity = defiled my land with lifeless forms, vile images of detestable gods/idols AND filled my inheritance/territory with carcasses of their detestable idols/abominations
• What's the big deal about sin? Isn't this just one person, with a guilty pleasure? These are questions I wondered about. BSF children's program had a good way of teaching, "the world says [it's no big deal, you were born that way], but God's word says [it's a massive deal, you were created for great purpose]. Sin Types: Iniquity, Transgression-trespass, Apostasy-backsliding
• An Idol is anything we trust in more than God.

Psalm 32:5, mentions sin, trespass, and iniquity and it's cure (Finally, I confessed all my sins to you

and stopped trying to hide my guilt (iniquity). I said to myself, “I will confess my rebellion (trespass) to the Lord.” And you forgave me! All my guilt is gone.)

• Iniquity is our thought process in our heads, premeditated choice: "Woe to those who devise wickedness and work evil on their beds! When the morning dawns, they perform it, because it is in the power of their hand."
• Iniquity unchecked leads to calloused heart (Matt 13:15 NIV) 
• and God leaving the person, "Therefore God gave them up in the lusts of their hearts to impurity, to the dishonoring of their bodies among themselves," Romans 1:24 ESV
• Iniquity is carried over generations (Rev 17:4, Gen 15:16). 
• Iniquity leads to unnatural affections, leads to a reprobate mind (Romans 1:28-32). 

Iniquity leads to transgression (rebellion/trespass)

• Transgression is to intentionally disobey. Apostasy-backsliding is a gross transgression, treason in which a "Christian" carries the name of God in vain.

Today if you hear his voice don't harden your heart, repent. Ask, seek and knock. Turn to the Lord and receive healing and forgiveness.
