1 Peter 1:22 says, “Since you have purified your souls in obeying the truth through the Spirit in sincere love of the brethren, love one another fervently with a pure heart.” Our hidden sin affects those around us. Case in point is Hebrews 12:15. One with bitter roots defiles those around them. 

Hidden sin is disobedience. In memorizing Romans 5, I realize afresh how Adam and Eve’s disobedience affected everyone born after them. Cain disobeyed: wrong sacrifice, killed his brother, then lied to God. Genesis 4:7 says, “…sin lies at the door. And its desire is for you, but you should rule over it.”

1 Corinthians 10:13 says that our temptations are the same as everyone else, and God makes the way of escape. We have no excuse. Romans 6:1 says, “…How shall we who died to sin live any longer in it?” At salvation we were freed from the bondage of sin. Hidden sin ~ enslaved to the idol in our heart.
